The slope is \frac{1}{3}.

Explanation:

The equation for a straight line is y=mx + c, where m is the gradient (or slope).

To find the gradient:
\text{gradient} = \frac{\text{rise}}{\text{run}}
m = \frac{y_1 - y_0}{x_1 - x_0}
m = \frac{9-7}{4 - (-2)}
m = \frac{9-7}{4 + 2}
m = \frac{2}{6}
m = \frac{1}{3}

The slope is \frac{1}{3}.
