The distance g(t) (in cm) between the gum and the sidewalk as a function of time t (in seconds) can be modeled by a sinusoidal expression of the form a *sin(b*t)+d. at t=0, the gum is half way between the ground and it's maximum height, at 35 cm. the gum reaches its maximum height of 70 cm from the ground pi/20 seconds later. find g(t)

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 .
