Both lines start at 0 and at 30 mins it is $6. It displays a ratio so that means every 10 mins they earn $2
y = -7/2x + 17/2
Slope = (-9 - - 2)/(5 - 3)
= -7/2
y-intercept: -2 - (-7/2)(3)
= -2 + 21/2 (-2*2+21)/2
= 17/2
25.920 W
Fill in the given number and do the arithmetic.
P = f(12) = 0.015(12^3) = 25.920 . . . . . watts
