Is the rate of change of the function 5? On a coordinate plane, a line with positive slope goes through points (negative 2, 0) and (1, 2). Yes, because y changes by 5 every time x changes by 1. Yes, because y changes by 1 every time x changes by 5. No, because y does not change by 5 every time x changes by 1. No, because y does not change by 1 every time x changes by 5.
