What is the slope of any line perpendicular to the line passing through #(2,7)# and #(5,2)#?
The line has slope
The slope of a line is the "rise" over the "run". That is, the change in the elevation divided by the distance between the measurements of elevation. In this example, by going from x=2 to x=5, a distance of 3, the elevation falls from 7 to 2, a change of -5. So, the slope of the line is
