Question 21

Write the equation of the line that passes through the point (-2,5) and is PERPENDICULAR to the line
y=1/2x+5.
Write your answer as a fraction in simplest form. Use the "/" as a fraction bar.

Answer 1

y=-2x+1

Explanation:

Perpendicular lines have slopes that are negative reciprocals of one another. slope 1/2 perpendicular will be -2/1=-2

y-5=-2(x-(-2))

y-5=-2(x+2)

y-5=-2x-4

y=-2x-4+5

y=-2x+1
