Answer:

B: 4x + 5y = -20; if x = 0, y = -4; if y = 0, x = -5 This matches the graph

Explanation:

One way of doing this problem is to find the actual x- and y-intercepts of each of the four given functions, and then to compare the results to the graph.

A: 4x - 5y = 20; if x = 0, y = -4; if y = 0, x = 5 Does not match graph

B: 4x + 5y = -20; if x = 0, y = -4; if y = 0, x = -5 This matches the graph

C: 5x - 4y = 20; if x = 0, y = -5; Does not match graph

D: 5x + 4y = -20; if x = 0, y = -5; Does not match graph
