Please help me out~ Purchasing the correctly sized BMX bike is based on the height of the rider. In order to fit a customer, the salesman can use the equation b=0.29h + 1.35 where b is the size of the BMX bike frame in inches and his the height of the rider in inches. Which sentence explains the slope in the equation? O As a rider increases one inch in height, the bike frame increases 0.29 inches. The heighi of the rider gets multiplied by 0.29. The bike frame increases 0.29 inches for every 1.35 inches of the rider's height. As a rider's height increases 1.35 inches the bike frame increases one inch.​
