Question

Find the equation of the line passing through the point (-1, -2) and perpendicular to

the line y = -1/2x + 5.
A) y = 2x
O B) y = -1/2x - 5/2
O C) y = -1/2x
OD y = 1/2x - 5,2

Answer 1

The answer is A y=2x

Answer 2

A) y = 2x

Explanation:

The slopes of perpendicular lines are negative reciprocals.

The given line has slope -1/2.

The negative reciprocal of -1/2 is 2.

The only choice with slope = 2 is choice A.

y = 2x does include point (-1, 2).

Answer: A) y = 2x
