A rocket is launched vertically from the ground with an initial velocity of 64 t/sec (a) Write a quadratic function
that shows the height, in feet, of the rocket seconds after it was
launched.
(b) Graph (t) on the coordinate plane.
Part c) use your graph from part three (b)to determine the Rockets maximum height, the amount of time it took to reach its maximum height, and determine the amount of time it was in the air.

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 .
