Question

Identify the slope for (7 , 15) and (0 , 15).

Answer 1

The slope of a line can be calculated with the following formula:

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

You can notice that it is the difference between the y-coordinates and the difference between the x-coordinates of two points on that line.

For this case, knowing these points:

`\begin{gathered} (7,15) \\ \mleft(0,15\mright) \end{gathered}`

You can say that:

`\begin{gathered} y_{2\text{ }}=15 \\ y_1=15 \\ x_2=0 \\ x_1=7 \end{gathered}`

Now you can substitute values into the formula and the evaluate:

`\begin{gathered} m=(15-15)/(0-7) \\ m=(0)/(-7) \\ m=0 \end{gathered}`

Therefore, the slope is 0:

`m=0`
