Answer the question because i don’t understand can you answer

y= 2x+7

Step-by-step explanation:

They are all pretty much want you to create the equation so the formula they want is y=mx+b format.

First problem(1,9) slope 2

Y=mx +b

Where y is 9,x is 1 and slope (m) is 2.

Now solve for b using equation

Y=mx +b

9= 2(1)+b

9=2+b

9-2=b

7=b

Now you can create equation

Y= 2x+7

Prob.4

(3,-6) and (-1,2)

First find slope

M= y2-y1/x2-x1

M= 2-(-6)/-1-3

M = 8/-4

M= -2

Your slope "m" is -2

Now do as problem 1 get one of the points and your slope to get equation .

(3,-6) slope -2

Y=mx+b

-6= -2(3)+b

-6= -6+b

-6+6=b

0=b

Y= -2x

Problem 7

(5,13) (10,14)

You solve this one as problem 4 same steps that I did above .

Problem 8 is also the same as steps in problem 4

( 2,160) and ( 2.75,220)

I hope this helps you
