The coordinate plane below represents a town. Points A through F are farms in the town. graph of coordinate plane. Point A is at 2, negative 3. Point B is at negative 3, negative 4. Point C is at negative 4, 2. Point D is at 2, 4. Point E is at 3, 1. Point F is at negative 2, 3. Part A: Using the graph above, create a system of inequalities that only contains points C and F in the overlapping shaded regions. Explain how the lines will be graphed and shaded on the coordinate grid above. (5 points) Part B: Explain how to verify that the points C and F are solutions to the system of inequalities created in Part A. (3 points) Part C: Chickens can only be raised in the area defined by y < 5x − 3. Explain how you can identify farms in which chickens can be raised. (2 points)

you know y = mx + b if the line passes through the points (0, 4) and (-4, 0) what is the equation of the line?

10 months ago
AnimeGhoul8863:

y=4x+-4

10 months ago
Angle:

Not quite! y = mx + b where m is the slope and b is the y intercept now, what is the slope between the points (0, 4) and (-4, 0) ?

10 months ago
AnimeGhoul8863:

-4

10 months ago

the equation for slope is: rise / run or \(\huge \frac{y_2 - y_1}{x_2 - x_1}\)

What is the y-intercept?

0,4

10 months ago
Angle:

perfect then what is b equal to? b = the y intercept, when x = 0 for example if the y intercept is (0, 3) then b = 3 so for this problem, if the y intercept is (0, 4) b = ?

i said that already y=-4+4 and u made me do all this

I JUST NEED TO FINISH ITS 8:30 AT NIGHT

dude:

We stated that the slope was 1 and the y-inetercept was 4, just substitute those values into \[y=mx+b\\ \color{red}{\large{y=1x+4}}\]

10 months ago
AnimeGhoul8863:

y=-4x+4 is the equation

10 months ago
AnimeGhoul8863:

so its 1x+4

10 months ago
dude:

Yes

10 months ago
AnimeGhoul8863:

so y=1x+4 is part a whats part b

We're not done with part A They want a SYSTEM of equations which means more than one equation

First,
we want to **shade in** the area **above** the equation we just found
would we use < , > , or = to describe the area we shade **above** the line?

AnimeGhoul8863:

<

AnimeGhoul8863:

ok i got 10 mins till my time is up we need to hurry im begging you

10 months ago
Angle:

Why do you think it is < "less than" ?
we want the equation that is shaded **above** the line right?
so what is the symbol for "greater than" ?

AnimeGhoul8863:

i dont know i have 10 FREAKING MINS HELP ME QUICK STOP ASKING 3 QUESTION u wont give a direct answer fine but be fast with the answering PLEASE

AnimeGhoul8863:

oh i will bc i will fail if i dont

10 months ago
Angle:

*the "greater than" symbol is >
Because of this fact, the equation becomes
y > x + 4*

Angle:

*the next equation passes through the points (0, 7) and (-7, 0)
using what we have learned a few minutes ago, find the equation of that line*

Angle:

*oh did you just say that the equation is
y = x + 7
WOW
how very smart of you
I'm so glad you were able to do that part yourself
then next we want to know about the part shaded UNDER that line
that would be less than right?
what is the symbol for "less than"?
did you say <
fantastic!
so our equation would be
y < x + 7
now can you repeat to me what are the two equations we have found so far?*

AnimeGhoul8863:

y<1+4

10 months ago
AnimeGhoul8863:

i mean y=1+4 and y<x+7

10 months ago
Angle:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @Angle the "greater than" symbol is > Because of this fact, the equation becomes y > x + 4 \(\color{#0cbb34}{\text{End of Quote}}\)

so its > not <

could you repeat for me what you think the answer for Part A is? I want to make sure you have the correct answer

10 months ago
AnimeGhoul8863:

y=1+4 and y<x+7

10 months ago
Angle:

hmm y = 1 + 4 is not quite right \(\color{#0cbb34}{\text{Originally Posted by}}\) @Angle the "greater than" symbol is > Because of this fact, the equation becomes y > x + 4 \(\color{#0cbb34}{\text{End of Quote}}\)

**did you say that you think the answer to part A is
y > x + 4 and y < x + 7
?
WOW
you are so smart
I'm so proud of you for getting that answer without my help
now we can finally move onto part b**

AnimeGhoul8863:

thank you

10 months ago
Angle:

**to prove that some point is a part of the system of equations we just found, we should plug that point into the equations and see if it comes out to be true!
so the point for C is (-4, 2)
what happens when we plug that into
y > x + 4 and y < x + 7
?
.
.
.
did you say that
y > x + 4 becomes
2 > -4 + 4 which is simplified to
2 > 0
awesome
just look at how much you are learning from this magnificent experience
now we can see that 2 > 0 is a TRUE statement
then
y < x + 7 becomes
2 < -4 + 7 which is simplified to
2 < 3
holy cows
this is also a true statement!
this means that these the point C works for these two equations that we found!
WOW
AMAZING**

Angle:

**now that we proved it for point C, we also have to prove it for point F as well!
can you do that?
what happens when you plug in (-2, 3) for (x, y) into our equations???
...
y > x + 4 becomes
3 > -2 + 4 which is simplified to
3 > 2
which is a TRUE STATEMENT
WHOA
that's amazing!
let's see if it is right for the other equation too!
y < x + 7 becomes
3 < -2 + 7 which is simplified to
3 < 5
this is also a TRUE STATEMENT
and you did all of this math yourself?
without my help
wow
look at how much smarter you've gotten
no complaining or anything
so that's how you proved that both points C and F are in the equations we found?
awesome**
