Kerry is skateboarding down a hill. The top of the hill is 4 feet above street level, and after traveling 3 yards, her height is 2 ft. Let y represent her height above street level, in feet, and x represent the distance she has traveled, in yards. Write an equation to represent Kerry's height, in slope-intercept form.

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
