Find the slope of the line that passes through the points (3, 5) and (-1, -7).

Step 1 ：First, we apply the formula for the slope of a line which is \(m = \frac{y_2 - y_1}{x_2 - x_1}\)

Step 2 ：Substitute the given points into the formula, we get \(m = \frac{-7 - 5}{-1 - 3}\)

Step 3 ：Simplify the expression, we get \(m = \frac{-12}{-4}\)
