Answer:
y = -2x + 24
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
m - slope
b - y-intercept
Step 1: Define
Random Point (7, 10)
Perpendicular to y = 1/2x - 9
Step 2: Find slope of perpendicular line
The perpendicular slope is the negative reciprocal of the given slope.
m = -2
y = -2x + b
Step 3: Find y-intercept b of perpendicular line
10 = -2(7) + b
10 = -14 + b
b = 24
Step 4; Write perpendicular line
y = -2x + 24
