In Problems 7โ22, solve each inequality.
Match each graph to one the following functions.
If the independent variable in a line of best fit is credit score, and the dependent variable is the interest rate on a used car loan, then the slope is interpreted as โif credit score increases by point, the interest rate will (increase/decrease) by percent, on average.
