Which graph represents the function y= 2x-4? sty すす0-3xits : : os : ; -32pr ftーvetーtt it tie。pttーt-it-t +--+-

You have the y-intercept of -4. That means that the line will go through the point (0, -4). Choices B and C do that. Plug in 1 for x and find y.

y = 2x - 4

y = 2 * 1 - 4

y = 2 - 4

y = -2

In graph B, when x = 1, y = -3.5,  which is incorrect.

In graph C, when x = 1, y = -2

Graph C is the correct answer.
