Question 80 • Algebra II

Which graph represents y is equal to negative 2 x ?

Answer

Image with description On a coordinate plane with x and y axes marked with negative 6 to 6, a straight line goes from quadrant 3 to quadrant 1. It passes through the points (negative 4 comma negative 2), (negative 2 comma 0), (0 comma 2) and (2 comma 4).

Explanation

For y = −2x, each y-value is −2 times its x-value. The line passes through (0, 0), and when x = 2, y = −4; when x = −2, y = 4. Choice C passes through those points and slopes downward from left to right, so it represents y = −2x.
