By definition, the slope of the line is defined as: m = (y2-y1) / (x2-x1) Substituting the values m = ((14) - (- 16)) / ((4) - (- 2)) = 5 Note that 5 is the same value as the slope of the line in function g (x) = - 6 + 5x The slope of the line will always be constant for any pair of points. answer the average rate of change is 5
