Answer

B

Work Step by Step

Graph A does not go through the given point of $(1,3)$ Graph C does not go through the given point of $(1,3)$ The instructions say that, when the x-value increases by 3, the y-value decreases by 4. Thus, another point on the line is $(1+3,3-4)$, or $(4,-1)$. The y-value for the x-value of 4 (on Graph D) is between 0 and 1. The y-value for the x-value of 4 (on Graph B) is -1. This matches what we determined above.
