Slope is 0.75, a a very steep rising incline of 75%.

  • The line rises at 36.87 degrees from the horizontal.
  • For every 4 units across, the line moves 3 units vertically, giving a hypotenuse of 5 units.

Next stepTo convert this slope into the angle of elevation in radians, divide the degree value by 57.296. To find rise for any run, multiply slope by the desired run length.
