Answer:
-(9)/(2), -4, -3, -(11)/(4), -2

Explanation:

slope = m


m=(y_2-y_1)/(x_2-x_1)=(-7-9)/(-1-(-5))=-4

y = mx + b, (-5,9), (-1,-7), m = -4; (does not matter which point you plug in)


y=mx+b\\9=-4(-5)+b\\9=20+b\\b=-11\\y=-4x-11

(now plug in each y value into the equation above)


7=-4x-11\\18=-4x\\x=-(9)/(2)\\\\5=-4x-11\\16=-4x\\x=-4\\\\1=-4x-11\\12=-4x\\x=-3\\\\0=-4x-11\\11=-4x\\x=-(11)/(4) \\\\-3=-4x-11\\8=-4x\\x=-2
