Question

The graph shows the number of paintballs, y, a machine launches in x seconds. Which expression can be used to calculate the rate per second at which the machine launches the balls? (1 point)

120 over 5
5 over 120
5 over 30
30 over 5​

Answer 1

Option B.) 12/2 (´⌣`ʃƪ)

Explanation:

The rate of a linear equation is equal to the slope m

The slope is equal to

points (2,12) and (4,24)

m=(24-12)/(4-2)

m=12/2

m=6 balls/sec
