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

Worked solution (try it first)

Gradient is the change in $y$ over the change in $x$ , in the same order: $\dfrac{-3 - (-7)}{-2 - 5}$ .
The top is $4$ and the bottom is $-7$ .
So the gradient is $-\frac47$ , option C.
