On Valterri’s last practice day, the team tracks his laps and total time on a graph, shown below. The team analyst also creates an equation from the race data, written as y=3.3x, where y = total time in minutes and x = the number of laps. Do the unit rates from the graph and the equation match? Why or why not?

Which term best describes the association between variables a and b? no association a negative linear association a positive linear association a nonlinear association a scatterplot with an x axis labeled, variable a from zero to ten in increments of two and the y axis labeled, variable b from zero to one hundred forty in increments of twenty with fifteen points in a positive trend.

Factor the expression using gcf 9b+45
