Question

Calculate the slope of a line the -1,2 and 0,8

Answer 1

m = 6

Explanation:

8-6 = 6

0-(-1)= 1

6/1 = 1

Answer 2

`\bf (\stackrel{x_1}{-1}~,~\stackrel{y_1}{2})\qquad (\stackrel{x_2}{0}~,~\stackrel{y_2}{8}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{8}-\stackrel{y1}{2}}}{\underset{run} {\underset{x_2}{0}-\underset{x_1}{(-1)}}}\implies \cfrac{6}{0+1}\implies 6`
