We use y=mx+c we know that c= 4 A’s this is the y intercept . Next we need to work out the gradient(m). For every two squares along we go three squares up. This means are gradient is 1.5. Finally we input are values into the equation y=1.5x+4
We are given

Since, we have to solve for F
so, we will isolate F on anyone side
step-1:
Multiply both sides by 60


step-2:
Divide both sides by 11


step-3:
Add both sides by 32


so, we get
