The slope of the line that goes through two points (x_1, y_1) and (x_2, y_2) is:

\dfrac{y_1-y_2}{x_1-x_2}

The two points we are given is (7,9) and (2,12). Substitute these values into the formula for the slope

=\dfrac{12-9}{2-7}

Simplify

=\dfrac{3}{-5}

Simplify again

=-\dfrac{3}{5}

This should be your answer. Let me know if you need any clarifications, thanks!
