Multiple Choice

A laboratory technician is calculating the slope of a trend line between two experimental data points: (3,1)(-3, -1) and (2,2)(2, -2). When applying the slope formula m=y2y1x2x1m = \frac{y_2 - y_1}{x_2 - x_1}, what is the correct numerical value for the denominator (x2x1x_2 - x_1) as shown in the first step of the procedure?
