If slope = 2 for a line on a graph with x on the horizontal axis and y on the vertical axis, then if
A)x decreases by 4, y decreases by 8
B)x = -4, then y = -2
C)y decreases by 4, x decreases by 8
D)x = -4, y = -8
E)x increases by 4, y decreases by 8

Question

The slope of 2 means that for every 1 unit decrease in x, y decreases by 2 units. Therefore, if x decreases by 4, y decreases by 8 (4 * 2 = 8).
