SOLUTION: The rate of change of a car is decreasing linearly by 10 miles per hour. Before the car started to slow down, the car was traveling at 50 miles per hour. Can you use a linear model

Question 840167: The rate of change of a car is decreasing linearly by 10 miles per hour. Before the car started to slow down, the car was traveling at 50 miles per hour. Can you use a linear model to represent the cars speed as a function of time and if so, why? What is the value for the slope and the y-intercept?

Hi

 y = -10x + 50, x is the number of hours & y is the speed in mph

value for the slope is  and the y-intercept is
