The gradient of the straight line joining the points P(5, -7) and Q(-2, -3) is


Question

The gradient of the straight line joining the points P(5, -7) and Q(-2, -3) is

Options

A) \(\frac{1}{2}\)

B) \(\frac{2}{5}\)

C) \(-\frac{4}{7}\)

D) \(-\frac{2}{3}\)

The correct answer is C.

Explanation:

PQ = \(\frac{y_1 - y_0}{x_1 - x_0}\) = \(\frac{-3 - (-7)}{-2 - 5}\) = \(\frac{-3 + 7}{-2 - 5}\) = \(\frac{4}{-7}\)
