A ramp of 13 feet in length is constructed in front of a house that is at a height of 5 feet from the ground. What is the horizontal distance between the front door and the point where the ramp touches the ground?

If you picture it, it will be a right angled triangle. This means you can use the Pythagorean theorem.

The hypotenuse is 13ft and one side is 5ft

So

13ft^2 - 5ft^2 = 144

Square root 144 to get 12

Therefore the distance is 12ft

Hope this helps! Any questions let me know :)

Just divide the x axis (the top) by 2 or multiply the y axis (the bottom) by 2

The answer is: y would equal 3 because if you simplify the equation then it would be y= 3x+9 and if you divide 3x and 9 by 3 it would equal 3. y= 3
