A cab company charges a fixed amount, plus a fee based on the distance traveled. The rate chart for the company is shown:
Rate Chart
Distance traveled (miles) (x) |Cost (dollars) (y)
0 | 8
1 | 11
2 | 14
The fixed amount is always the y-axis in these types of problems, or what y equals when x equals 0. In this case, it is 8 dollars. The equation would be 3x+8.
