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