Question

Find the slope of the line passing through the points $(3,-2)$ & $(7,-2)$

Answer 1

$(x1,y1)=(3,-2)$

$(x2,y2)=(7,-2)$

$\text{slope}=\frac{y2-y1}{x2-x1}$

$\text{slope}=\frac{-2-(-2)}{7-3}$

$\text{slope}=\frac{-2+2}{7-3}$

$\text{slope}=\frac{0}{7-3}$

$\text{slope}=0$

Hence the $\text{slope}=0$
