To find the rise between both points, identify the vertical distance over the Y-axis between them.
Similarly, the run can be found by identifying the horizontal distance over the X-axis.
As shown in the image, the rise between both points is -5 and the run between both points is +5.
The slope of a line is the quotient between its rise and its run:

Then, the slope of this line is -1.
Therefore, the answers are:
Rise: -5
Run: 5
Slope: -1
