1. According to the situation, the function that represents the cost of a cab ride is:
[tex]y=2.25x+2.5[/tex]2. The change of rate is represented by the fee per mile, in this case it is 2.25.
To travel 1 mile costs $4.75. To find it, replace x for 1 in the function:
[tex]\begin{gathered} y=2.25(1)+2.5 \\ y=4.75 \end{gathered}[/tex]3. The initial value (y intercept) is 2.5. This represents the base fee of the ride.
