The profile of the cables on a suspension bridge may be modeled by a parabola. the central span of the bridge is 1240 m long and 135 m high. the parabola y equals 0.00035 x squared gives a good fit to the shape of the cables, where startabsolutevalue x endabsolutevalue less than or equals 620 , and x and y are measured in meters. approximate the length of the cables that stretch between the tops of the two towers.

Iam trying to solve a linear equation for the shoe size of someone 84" tall taking into consideration example 1 is 69" tall with a shoe size of 9 and example 2 is 72 inches tall with a shoe size of 11. i understand that the equation should be y=mx+b and that on the graph the answer is (3,2) but i just don't understand how to create the equation to solve for 84-inches and 60-inches tall questions. after two days, i need .
