The equation needing to be solved is ( -5,10) and (3,-6). This needs to be wrote in the slope intercept form.
:
Use the slope formula: m = %28%28y2-y1%29%29%2F%28%28x2-x1%29%29
Assign the values as follows
x1=-5; y1=10
x2=3; y2=-6
Find the slope
m = %28%28-6-10%29%29%2F%28%283-%28-5%29%29%29 = %28-16%29%2F8 = -2 is the slope
:
Use the point/slope form y - y1 = m(x-x1), we know m=-2
y - 10 = -2(x - (-5))
y - 10 = -2(x + 5)
y - 10 = -2x - 10
y = -2x - 10 + 10
y = -2x, this is the slope intercept form (intercept is 0)

Confirm this when x = -5,
y = -2(-5)\
y - 10
and when x = 3
y = -2(3)
y = -6
