7. Perpendicular slope : -2
Y = -2x + b
Plug in the point (2, -4)
-4 = -4 + b, b = 0
Equation: y = -2x
8. Perpendicular slope: -2
Y = -2x + b
Plug in the point (-3,5)
5 = 6 + b, b = -1
Equation: y = -2x - 1
9. Perpendicular slope: -3/2
Y = -3/2x + b
Plug in the point (-2, 4)
4 = 6 + b, b = -2
Equation: y = -3/2x - 2
10. Perpendicular slope: 1/2
y = 1/2x + b
Plug in the point (-4, 0)
0 = -2 + b, b= 2
Equation: y= 1/2x + 2
Those are what I got :)
