Question

What is the slope formula (-13,9) and (20,9)?

Answer 1

The slope formula for two points is

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

where these values come from the given points:

`\begin{gathered} (x_1,y_1)=(-13,9) \\ (x_2,y_2)=(20,9) \end{gathered}`

By substituting these values into the slope formula, we have

`\begin{gathered} m=(9-9)/(20-(-13)) \\ m=(0)/(33) \\ m=0 \end{gathered}`

so, the slope is equal to zero. This imply that the line between these points is horizontal.
