A. The graphs have the same shape. The y-intercept of y=|x| is 0, and the x-intercept of the second graph is -15.
B. The graphs have the same y-intercept. The second graph is steeper than y=|x|
C. The two graphs are the same.
D. The graphs have the same shape. The y-intercept of y=|x| is 0, and the y-intercept of the second graph is -15.
