Answer 1

@snowflake0531

Answer 2

The slope intercept form is
\[y=mx+b\]
where m is slope, b is y-intercept
with 2 pairs of coordinate points, we can first find slope, and then use the slope and one pair of coordinate points to find y intercept


Do you know how to find slope?

Answer 3

Ok so would the y would be: \[m=\frac{ 13-10 }{ 14-8 }=\frac{ 3 }{ 6 }\]

Answer 4

Not y ._. m

Answer 5

Yes and what is 3/6 simplified

Answer 6

1/2

Answer 7

Do I solve for b now-

Answer 8

So we have
\[y= \frac{ 1 }{ 2 } x + b\] we can take one of the coordinate points, let's take \[(8,10)\] so then we have \[10 = \frac{ 1 }{ 2 } (8) +b\] can you find b?

Answer 9

\[10=\frac{ 1 }{ 2}(8)+b\]\[10=4+b\]\[10-4;4-4\]\[6=b\]

Answer 10

yep so we have our equation
\[y= \frac{ 1 }{ 2 } x + 6 \]

Answer 11

Ok so is that the answer-?

Answer 12

yes to number 1

Answer 13

Ok.

Answer 14

2. \[m=\frac{ 5-17 }{ 9-5 }=\frac{ -12 }{ 4}\]

Answer 15

Yes, so it's -3
now can you plug that slope and one coordinate point into the equation y=mx+b?

Answer 16

\[17=-3(5)+b\]\[17=-15+b\]\[17+15;-15+15\]\[32=b\]

Answer 17

Yep, so what's your equation?

Answer 18

y=-3x+32

Answer 19

Yep you got it

Answer 20

For part A of the 3rd, I think you can do that

Answer 21

And for C I kind of graphed on Desmos so I got

Answer 22

And for B, you can write that yourself

Answer 23

What does it mean by "on the line " e.e

Answer 24

Like since we have the line, just look at that, in write 2 coordinate points

Answer 25

e.e I don't get it

Answer 26

Bruh look at the line lol....
And look at all the coordinates, like every point that is on the line

Answer 27

I don't get it

Answer 28

Since you did part A, what is the line you drew?

Answer 29

Answer 30

Yes that works

Choose two points closest to the line

Answer 31

(14,17) (8,28)

Answer 32

Perf

Now you have to find the slope using those two points

Point 1 is (8,28)
Point 2 is (14,17)

Do you know how to find that?

Answer 33

^^ is also your answer to b.

Answer 34

Ok so that would be \[m=\frac{ 17-28 }{ 14-8 }=\frac{ -11 }{ 6 }\] then \[28=\frac{ -11 }{ 6}(8)+b\]

Answer 35

yes`

Answer 36

\[28=\frac{ -44 }{ 3 }+b\]

Answer 37

I can't simplify -44/3

Answer 38

Don't simplify it then-
Just keep it that way and find b

Answer 39

e.e Would I turn the 28 into an improper fraction for that-?

Answer 40

Sure, yea make it something over 3

Answer 41

\[\frac{ 84 }{ 3 }+\frac{ 44 }{ 3 }; \frac{ -44 }{ 3 }+\frac{ 44 }{ 3 }\]\[\frac{ 128 }{ 3}=b\]

Answer 42

Sure yes, so with your slope and y-intercept what's your line?

Answer 43

\[y=\frac{ -11 }{ 6 }x+\frac{ 128 }{ 3 }\]

Answer 44

yes, that's your equation

Answer 45

Oki thx snow and dudet

Answer 46
