Question

I need the slope of (5, -3) and (8,-3)

Answer 1

first off, let's notice that the y-coordinates are the same for both points, meaning is really just a horizontal line, and its slope is 0, however, let's go through the rigamarole

`(\stackrel{x_1}{5}~,~\stackrel{y_1}{-3})\qquad (\stackrel{x_2}{8}~,~\stackrel{y_2}{-3}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{\textit{\large rise}} {\stackrel{y_2}{-3}-\stackrel{y1}{(-3)}}}{\underset{\textit{\large run}} {\underset{x_2}{8}-\underset{x_1}{5}}} \implies \cfrac{-3 +3}{3} \implies \cfrac{ 0 }{ 3 } \implies \text{\LARGE 0}`
