Question 34 • Mathematics I

Which graph represents the function y is equal to 2 x minus 4 ?

Answer

A

Image with description A coordinate plane with a line passing through (negative 4, 0) and (0, 2).

B

Image with description A coordinate plane with a line passing through (0, negative 4) and (2, 0).

C

Image with description A coordinate plane with a line passing through (negative 4, 0) and (negative 2, 4).

D

Image with description A coordinate plane with a line passing through (0, negative 4) and (4, negative 2).

Explanation

In y = 2x − 4, the y-intercept is −4, so the graph passes through (0, −4). Setting y to 0 gives 0 = 2x − 4, so x = 2 and the graph also passes through (2, 0). Choice B shows a line through those points.
