QUESTION # 14
What is the slope of this data?

Answer 1

to get the slope of any straight line, we simply need two points off of it, let's use the points in the picture below.

`(\stackrel{x_1}{18}~,~\stackrel{y_1}{4})\qquad (\stackrel{x_2}{27}~,~\stackrel{y_2}{6}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{6}-\stackrel{y1}{4}}}{\underset{run} {\underset{x_2}{27}-\underset{x_1}{18}}} \implies \cfrac{2 }{ 9 }\implies 0.\overline{22}`

Answer 2

a) 0.22...

Explanation:

m=y2-y1/x2-x1

m=6-4/27-18

m=2/9 = 0.22..
