Interpret intercepts and starting values in contextual linear situations.
Build a representation that shows the special value
Problem
A bike rental costs \(\$6\) at \(0~\text{miles}\). Express the starting-value point in the form \((\text{miles},~\text{cost})\).
Big Picture
What this problem is really about
A coordinate point can display a starting value only when its first entry represents the input and is set at the beginning. Translate the requested coordinate order into a sentence, place the zero-input condition in the input position, and pair it with the cost already present then. This preserves both meaning and order without treating the starting charge as a rate.
