the carin years, x. The equation of the line that models the data in
the scatter plot is given by y = -2500x + 26000. This equation is
shown in the scatter plot.

a. where in the equation do you see the slope? what does it represent?
b. where in the graph do you see the y-intercept?what does it represent?
c. ava said the slope of the line -2500 and that it describes the rate at which the age of the car is decreasing. why is she inccorrect?
