slope=rise%2Frun Start with the slope formula. The "rise" is the change in vertical position and the "run" is the change in horizontal position.


slope=2.6%2F7.5 Plug in the given values


slope=0.34667 Divide


So the slope is approximately 0.34667 which means that the grade is roughly 34.667% (multiply by 100 to make a percentage)
