Katie purchased a new car for $27,599. This make and model straight line depreciates for 13 years. 1. Identify the coordinates of the x- and y-intercepts for the depreciation equation. Determine the slope of the depreciation equation. y-intercept: (0, maximum car value) x-intercept: (maximum lifespan, 0) + y-intercept:( x-intercept: Ax Slope ratio = Ду 27.599-0 Slope ratio = 0-13 Katie's new car depreciates at a rate of a year.
