First I’ll write down the points given (-4,5),(-1,-7.5)
Second, I will find the slope, and the slope formula is y2-y1/x2-x1
Third, I’ll plug in the points into the formula -7.5-5/-1-(-4) = -12.5/3= -37.5
Fourth, you could plug in the points in slope intercept form y=mx+b or point slope form y-y1=m(x-x1), I’ll use slope intercept form.
5=-37.5(-4)+b
5=150+b
-145=b
b=-145
So your answer will be -145.
