Find the slope of the line that passes through Point A $\left(-1,0\right)$(1,0) and Point B $\left(0,3\right)$(0,3) using $m=\frac{\text{rise }}{\text{run }}$m=rise run .

Find the slope of the line that passes through Point A $\left(2,-6\right)$(2,6) and the origin using $m=\frac{\text{rise }}{\text{run }}$m=rise run .

Find the slope of the line that passes through Point A $\left(3,5\right)$(3,5) and Point B $\left(1,8\right)$(1,8), using $m=\frac{y_2-y_1}{x_2-x_1}$m=y2y1x2x1.
