Question

A line is perpendicular to y=-1/2x-1 and intersects the point (6, 9). What is the equation of this perpendicular line?

Answer 1

Answer:

y = 2x - 3

Step-by-step explanation:

slope of perpendicular line must be 2

use (6,9) and slope of 2 to find 'b', or the y-intercept

9 = 2(6)+b

9 = 12 + b

-3 = b

y = 2x - 3
