Answer

remember the slope formula.

if you have two known points P1 and P2 of a line, the slope is given by:

$\begin{gathered} P1(x_1,y_1)\text{ and} \\ P2(x_2,y_2) \\ \text{slope}=(y_2-y_1)/(x_2-x_1) \end{gathered}$

Step 1

let

P1(15.147)

P2(21,205.8)

Step 2

replace,

$\begin{gathered} \text{slope}=(205.8-147)/(21-15) \\ \text{slope}=(58.8)/(6) \\ \text{slope}=9.8 \end{gathered}$

so, the slope is 9.8
