#### Storyboard Text

• Well, let's do some math. To find how much it would cost me monthly, just use the equation c= .12d + 330. The c represents cost, and the d represents the distance traveled!
• How much does the car you own cost you each month?
• So, you multiple the number of kilometers traveled by 0.12 and add 330! If I travel 1000 km a month, it will cost me about \$140. And if I travel 2000 km? It will cost me \$570.
• So the distance -intercept would be 1 km for every 0.12 cents?? That means that the cost depends on how far you drive.....
• So how is that suppose to help me?
• Thinking back to the work we have already done, I could drive 2,250 km without exceeding \$600.
• Then how far could you drive without exceeding a monthly cost of \$600??
• Say I were to graph this situation, what would be the cost-rate intercept??
• The cost-rate intercept would be \$330!
• Exactly!
• One last question! What would be the slope??
• Well, the slope would be .12 cents per km! This number represents the rate at which the rate of change/information changes!
