Answer:
y = -8
Step-by-step explanation:
Perpendicular to 7x-14=21 that passes through (2,-8): y = -8
The equation is a vertical line, so the slope is infinity.
m = infinity
The perpendicular slope to 0 is infinity
Mp = 0
Compute the line equation y=mx + b for the slope m=0 and passing through (2,-8)
compute the y intercept: b = -8
Construct the line equation y = mx + b, where m = 0, and b = -8
