The graph shows the number of paintballs a machine launches, y, in x seconds:

(graph shown below)

which expression can be used to calculate the rate per second at which the machine launches the balls?

12/2
2/12
48/2
2/48

Which is an accurate comparison of the two data sets? the commute to work is typically shorter and more consistent than the commute home. the commute to work is typically shorter but less consistent than the commute home. the commute to work is typically longer and less consistent than the commute home. the commute to work is typically longer but more consistent than the commute home.
