Answer:
1) y=1/2x+4 and y=-2x-4
2) y-9 = -2(x+7)
Step-by-step explanation:
1) Perpendicular lines must have reciprocal slopes. So, the sign must be switched and the numerator and denominator must be switched.
2) Point-slope form is [tex]y-y_{1} = m(x-x_{1})[/tex]
So plug the slope and point in.
y - 9 = -2 (x - (-7))
y-9=-2(x+7)
