Question

What is the unit rate depicted in the graph?

On a coordinate plane, a graph titled Lap Times has minutes on the x-axis and Laps on the y-axis. A line goes through points (4, 3) and (8, 6).
0.75 laps in one minute
1.25 laps in one minute
3 laps in 4 minutes
4 laps in 3 minutes

Answer 1

Slope = (6 - 3)/(8 - 4) = 3/4 = 0.75. Since x = minutes and y = laps, the unit rate is 0.75 laps per 1 minute (which is the same as 3 laps in 4 minutes).
