The slope (m) of a line containing two points is computed as follows:


m\text{ = }(y_2-y_1)/(x_2-x_1)

where (x1, y1) and (x2, y2) are the coordinates of the given points.

In this case, the points are (3, 5) and (-7, 9). Replacing into the formula:


m\text{ = }\frac{9\text{ - 5}}{-7\text{ - 3}}\text{ = }(4)/(-10)

which can be simplified to -2/5 dividing numerator and denominator by 2.
