Find the slope of the straight line passing through

(a) $\mathrm{E}(-1,3)$ and $\mathrm{F}(3,11)$

(b) $\mathrm{E}(-1,3)$ and $\mathrm{G}(4,-2)$

(c) $\mathrm{E}(-1,3)$ and $\mathrm{H}(49,3)$

Step 1

1 of 4PART A:

$\begin{align*} m &= \dfrac{\Delta y}{\Delta x}\\ &= \dfrac{y_2-y_1}{x_2-x_1}\\ &=\dfrac{11-3}{3-\left(-1\right)}\\ &=\dfrac{8}{4}\\ &=2 \end{align*}$

Calculate the slope of the line that passes through these two points by dividing the difference in the $y$-coordinates over the difference in the $x$-coordinates.
