The question is really asking what the slope (m) of the line is. Here’s the answer:
Slope= the variable m
m=rise/run; m=change in y/change in x
We need to find the rate of how much the taxi driver charges per minute.
Therefore:
We need to pick a precise point on the line ( a precise point is a point with whole number x and y coordinates; no decimals or fractions).
We see that the point (6, 9) is precise.
A rate is a ratio in the form of a fraction that shows the relationship of change between two quantities: a/b.
So, the taxi costs 9 dollars / 6 minutes.
9/6 simplifies 2/3.
And thus, the taxi charges 2 dollars per 3 minutes
So, the answer is 9/6, which can be simplified to the furthest possibility, making it a unit rate.
Answer: 9/6
