D, because a histogram does not show individual data points
The slope-intercept form: y = mx + b
m-the slope
Ava took 5 minutes out of 60 in an hour to do half a mile
5×2=10
60/10=6mph
Damon took 3 minutes out of 60
3×2=6
60/6= 10mph
Reina took 4 minutes out of 60
4×2=8
60/8= 7.5mph
The 7 should be one's place...?
