The slope of a line that passes through two points (x1, y1) and (x2, y2) (Select all that apply.) ' can be written as Ay/Ax. ' is a measure of the average rate change of y with respect to x. ' is dy/dx. ' can be evaluated by y1 over x1. ' can be calculated by using the formula of "rise over run". ' can be determined by the change of y over the change of x. ' is the square root of the sum of (X2 - X1)2 and (y2 y1)2. " is a measure of the steepness of the line
