4 1/3 Rise over run you know, y1-y2 over x1-x2
slope = rise/run the ladder "rises" to 13 feet above the ground the ladder "runs" 3 feet from the base of the ladder to the tree so: slope = rise/run = 13/3
The slope of the ladder can be calculated using the formula for slope, which is the rise divided by the run. Given that the rise is 13 feet and the run is 3 feet, the slope is approximately 4.33. This means the ladder rises about 4.33 feet for every 3 feet of horizontal distance.
