Question

What is the slope of a line perpendicular to the line whose equation is y = 2x + 5?

slope = -1
slope = -
slope = -2

Answer 1

Is there a picture for this question?

Answer 2

When a line is perpendicular to another line, the slope will be the opposite of the reciprocal of the other.

In this scenario, a line is perpendicular to 2. The other line will be the opposite of the reciprocal of this line.

slope = -
`(1)/(2)`

Good luck!
