Find the slope of the line going through the points (7,13) and (7,6). Write your answer in simplest
form. If the slope is undefined, write "undefined".

The slope would be -1.

In order to find this answer use the equation m=y2-y1/x2-x1 to plug in the value of the points and subtract. Then , if you plug it in correctly, you would get -7/7 which simplifies to -1.

Hope this helped:)
