Answer:

y = 3/5x -4/5

Explanation:

We first need to find the slope

m = (y2-y1)/ (x2-x1)

=(-5-1)/(-7 -3)

= -6/-10

= 3/5

We can put this into the slope intercept form of the equation

y = mx+b where m is the slope and b is the y intercept

y = 3/5x +b

Using one of the point

1 = 3/5(3) +b

1 = 9/5 +b

Subtract 9/5 from each side

5/5-9/5 =9/5-9/5+b

-4/5 =b

Putting this back into the equation

y = 3/5x -4/5
