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.
Solutions 

You have been given the y-intercept of -4. The meaning of this is that the given line will go through the point (0, -4). Plug in 1 for x and find y.

[tex] y = 2x - 4 y = 2 * 1 - 4 y = 2 - 4 y = -2[/tex]


In graph C,=  x = 1, y = -2

Graph C is the correct answer.
