Answer:

y=4x+7

Step-by-step explanation:

You can find the slope of the line by using the formula of change and y over change in x. ∆y/∆x OR (y2-y1)/(x2-x1)

11-3=8

1--1=2

8/2=4

Let's plug in a y value 3.

3=4*-1+b

b=7

Once you found b rewrite your equation in slope intercept form.

y=4x+7

You can check this equation by plugging in the unused coordinate (1,11) and find it balances.
