Question

Find the slope of the line through each pair of points. (11, 1) (-7, 18)

Answer 1

Hello!

Explanation:

Slope formula:
`m=(Y^2-Y^1)/(X^2-X^1)`

Rise/run.

`(rise)/(run)`

`(18-1=17)/((-7)-11=-18)=(17)/(-18)`

Answer:
`=(17)/(-18)`

Slope is
`(17)/(-18)`

Hope this helps!

Answer 2

`\bf (\stackrel{x_1}{11}~,~\stackrel{y_1}{1})\qquad (\stackrel{x_2}{-7}~,~\stackrel{y_2}{18}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{18-1}{-7-11}\implies \cfrac{17}{-18}`
