1. The slope of our equation, because this is in slope-intercept form is just the
2. coefficient in front of the x, so that's the cost to make each nozzle. We know
3. that each nozzle costs \$2 to make, so m is just 2. This is the thing that's
4. going to determine how much the total amount of money spent or y will change as
5. the number of nozzles or x changes. Now that we know that m is equal to 2, we
6. can replace cost to make each nozzle with 2. Well, that looks even better. I am
7. so excited about where we're going with this equation.
