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