find the volume of a pyramid with a square base, where the side length of the base is 4.6 m and the height of the pyramid is 7.2 m. round your answer to the nearest tenth of a cubic meter

In order for the function to be linear, what must m be and why? m = 22 because the rate of change is 1. m = 20 because the rate of change is 3. m = 22 because the rate of change is -1. m = 20 because the rate of change is -3.
