Calculate the slope of each line using the points given. (15 s, 147m), (21 s, 205.8m)

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
