Question

Choose the equation for the relationship shown in the graph.

A) y = x + 50
B) y = x – 50
C) y = 50 - x
D) x = 50 - y

Answer 1

B) y = x - 50

Explanation:

It is B because the graph's y-intercept lies on the point (0, -50), hence the equation, y = x - 50. In addition, you can verify that B is the correct answer because the slope of the graph is positive, and so the x-value also must be positive.
