Answer:

The equation of your line is y=1x+2

Explanation:

first you take y2-y1/x2-x1

y2=-1 y1=5

x2= -3 x1= 3

that gives you your slope so (-1-5)/ (-3-3) = 1

y=mx+b

mx is your slope

y=1x+b

to solve for b you input your slope and one of your points (I used (3,5)

5=1(3) +b

solve for b and you get 2

then put your mx and b into the equation of a line

y=1x+2

and thats your answer

You can also check your work by using a graphing calculator and checking that the line goes through those two points.
