    consider this the slope of the entrance ramp to a doorway.G is at (0,2)and h is at(7,0)if each space on the graph paper represents 1 foot how tall is the ramp?

    we have to find the distance GH, we know that the distance between two points with coordinates (x2,y2) and (x1,y1) is \[D=\sqrt{(x2-x1)^2+(y2-y1)^2}\] here one point is 7,0 and other is 0,2 so \[D=\sqrt{(7-0)^2+(0-2)^2}\] we get \[D=\sqrt{49+4}\] or\[D=\sqrt{53}\]

    now in graph is space is equivalent to1 feet so the length of the ramp is \(\sqrt{53}\) feet
