Question

What is the slope of the line that passes through the points ( − 9 , 0 ) and ( − 17 , 4 )

Answer 1

Slope is y2-y1/x2-x1

4-0/-17-(-9)
4/-8
=-2

Answer 2

`(\stackrel{x_1}{-9}~,~\stackrel{y_1}{0})\qquad (\stackrel{x_2}{-17}~,~\stackrel{y_2}{4}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{\textit{\large rise}} {\stackrel{y_2}{4}-\stackrel{y1}{0}}}{\underset{\textit{\large run}} {\underset{x_2}{-17}-\underset{x_1}{(-9)}}} \implies \cfrac{4 }{-17 +9} \implies \cfrac{ 4 }{ -8 } \implies - \cfrac{1 }{ 2 }`
