Question

Algebra 1 Help Please!

Create your own equation written in standard form.

Determine any point that is a solution and will be on this line. Justify your answer algebraically.

Explain how to find the x- and y- intercept(s) using complete sentences. Write the intercepts as ordered pairs.

Rewrite the equation using function notation. Graph the function and show the intercepts.

Answer 1

HI :DDD

Answer 2

lol That's not the answer! :p

Answer 3

HI again :DDD

Answer 4

Well are you able to come up with an equation?

Answer 5

2x+7y=14 ?

Answer 6

Explain how to find the x- and y- intercept(s) using complete sentences.

^ to find x-int, plug in y=0

to find y-int, plug in x=0

Answer 7

x=1 y=1?

Answer 8

no...

2x+7y=14

^ to find x-int, plug in y=0.

Then, to find y-int, plug in x=0.

Answer 9

x=7

Answer 10

y=2

Answer 11

Sorry about that!

Answer 12

But you forgot "Write the intercepts as ordered pairs."

Do them one at a time.

Answer 13

(7,2)

Answer 14

I was going to warn you to not make that mistake.

^ to find x-int, plug in y=0... your x-intercept is x=2. Write it as an ordered pair.

Answer 15

(2,0)
(0,7)
?

Answer 16

Much better.

Answer 17

Notice that an x intercept can NEVER EVER EVER be (7,2), and neither can a y-intercept. Why?

Answer 18

Thank you! Because it can only be an x intercept and if you put (7,2) its a y intercept and an x intercept?

Answer 19

An x-intercept has to be on the x-axis, just like a y-intercept has to be on the y-axis.

(7,2) is never any kind of intercept. Get a graph, plot a point at (7,2) and see why.

Answer 20

Or, for a point to be an x-intercept, what must y be equal to?

Answer 21

The point isnt on the x-axis? and the y must be 0?

Answer 22

Exactly. What about for a y-intercept... What does x have to?

Answer 23

the x has to be a zero!

Answer 24

Exactly.

Learn this now, because I have algebra 2 students who don't understand this, and it makes me want to murder them :P

Answer 25

haha! Okay, I will try to remember that!

Answer 26

You better! Because if you somehow end up in my algebra 2 class, and complain to the cops that your algebra 2 teacher murdered you, I will point them to this and they'll say "Well, he did warn you... ". Cops probably don't listen to dead people anyway :P

Answer 27

hahaha! wow okay i will write it on a sticky note and post it to my forehead!!

Answer 28

Hahaha okay :)

And don't worry I wouldn't actually murder you :P but my god it is frustrating to have algebra 2 students, who don't even understand the basics of algebra 1.

Answer 29

lol I understand completely! I will make sure to go into Algebra 2, fully informed of this problem! Thank you soooo much for helping me on this problem! I have gymnastics practice so I have to go! I appreciate you helping me!

Answer 30

You're welcome! Good job :)
