Question

Jane started jogging home from 5 miles away, at a rate of 2 mph. Which equation in slope-intercept form represents Jane's distance from home?A.y = 2x − 5B.y = −2x + 5C.y = 2x + 5D.y = −2x − 5

Answer 1

Jane started jogging home from 5 miles away. Then she started at position -5 in her way to her house.

She is going toward her home, then the distance to her home (y ) decreases as she runs. That requires a positive slope.

Therefore, the answer is:

y = 2x − 5
