$\text{The slope of the line joining the points } (x_1,y_1) \text{ and } (x_2,y_2) \text{ is given by } m=\dfrac{y_2-y_1}{x_2-x_1}$.So, the slope of the line joining the points \(\left(-5,7\right)\) and \(\left(2,6\right)\) is \(\dfrac{\left(6\right)-\left(7\right)}{\left(2\right)-\left(-5\right)}\) = \(\dfrac{6-7}{2+5}\) = \(\dfrac{-1}{7}\) = \(-\dfrac{1}{7}\)The slope is negative, so the line is falling from left to right.
