Question

Find the slope of the line going through the points (-5,3)

and (2,3). Write your answer in simplest form.

Answer 1

`(\stackrel{x_1}{-5}~,~\stackrel{y_1}{3})\qquad (\stackrel{x_2}{2}~,~\stackrel{y_2}{3}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{3}-\stackrel{y1}{3}}}{\underset{run} {\underset{x_2}{2}-\underset{x_1}{(-5)}}} \implies \cfrac{0}{2 +5} \implies \cfrac{ 0 }{ 7 } \implies \text{\LARGE 0}`

notice, the y-coordinate is the same, so is a horizontal line.

Answer 2

y=3

m=riserun=ΔyΔxm=y2−y1x2−x1 m=3−32−−5m=07m = 0
