Determine the line that is perpendicular to y = 1/9x - 2/3

Answer 1

Hello there,

determine the line that is perpendicular to y = 1/9x - 2/3

Answer: First choice(Option A)

Answer 2

A

Explanation:

Perpendicular lines have a relationship between their slopes. Their slope are negative inverses of each other. This means is one is 3 then the negative reciprocal is the other or -1/3. The slope here is 1/9 so the perpendicular slope is -9. Slope is always attached to the x term so A is the solution.
