Question

Using the slope formula, find the slope of the line through the points (0, 0) and (5, 20).

Answer 1

The slope formula for 2 points is

`m=(y_2-y_1)/(x_2-x_1)`

where

`\begin{gathered} (x_1,y_1)=(0,0) \\ (x_2,y_2)=(5,20) \end{gathered}`

By substituting these values into the slope formula, we get

`\begin{gathered} m=(20-0)/(5-0) \\ m=(20)/(5) \\ m=4 \end{gathered}`

therefore, the slope is 4.
