Question

What is the slope of the line of the points (26,7) and (-39,12)

Answer 1

You can use the following formula to find the slope of a line:

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

Where these points are on the line:

`(x_1,y_1);(x_2,y_2)`

In this case, you have these two points:

`\begin{gathered} \mleft(26,7\mright) \\ (-39,12) \end{gathered}`

Then, you can set up that:

`\begin{gathered} y_2=12 \\ y_1=7 \\ x_2=-39 \\ x_1=26 \end{gathered}`

Therefore, substituting values into the formula and evaluating, you get:

`\begin{gathered} m=(12-7)/(-39-26) \\ \\ m=(5)/(-65) \\ \\ m=-(1)/(13) \end{gathered}`

Hence, the answer is: Option A.
