We need to find the gradient of the line passing through the points $P(2, -3)$ and $Q(5, 3)$.

1. Problem Description

We need to find the gradient of the line passing through the points $P(2, -3)$ and $Q(5, 3)$.

2. Solution Steps

The gradient of a line passing through two points $(x_1, y_1)$ and $(x_2, y_2)$ is given by the formula:

$m = \frac{y_2 - y_1}{x_2 - x_1}$

In this case, we have $(x_1, y_1) = (2, -3)$ and $(x_2, y_2) = (5, 3)$.

Plugging these values into the formula, we get:

$m = \frac{3 - (-3)}{5 - 2}$

$m = \frac{3 + 3}{3}$

$m = \frac{6}{3}$

$m = 2$

3. Final Answer

The gradient of the line is

2. Therefore, the answer is C.
