Q:
# The equation y = 8.5x - 77.5 is a linear model for data comparing thespeed that a car is going (x) to the stopping distance it takes for the car to stop(y). Speed is measured in mph and distance in feet. What is the averagestopping distance of a car going 45 mph?

Accepted Solution

A:

Answer:305 feetStep-by-step explanation:you only need to replace the given data into the equation.the value (y) is the one you are being asked to find and (x) is the given oneso:y=8.5(x)-77.5y=8.5(45)-77.5y=382.5-77.5y=305since the units are given, you instantly know that y=305feet
