You can put this solution on YOUR website! a steak has thickness w inches. Let T be the time it takes to broil steak. It takes 12 minutes to broil a one inch thick steak. For every additional inch of thickness, the steak should be broiled for 5 more minutes. Wrie an equation for T in terms of w.
You have two points: (1,12) (2,17)
slope = 5
The Equation will be T = mw+b
m=5 and T=12 when w = 1 to you can solve for b as follws:
12 = 5*1+b
b = 7
EQUATION:
T(w) = 5w + 7
