In Mathematics, the ratio of the price of two (2) goods that is represented on a graphed budget line is measured by its: slope.
<h3>What is a graph?</h3>
A graph is a statistical tool that is primarily used for the graphical representation of data by using both the horizontal and vertical lines, which are denoted as x-axis and y-axis respectively.
<h3>What is slope?</h3>
The slope of a line can be defined as the gradient of a line and it's typically used to describe both the ratio, direction and steepness of an equation of a straight line.
Mathematically, the slope of a line is given by the following formula;

In conclusion, the ratio of the price of two (2) goods that is represented on a graphed budget line is measured by its slope.

Answer: 
Step-by-step explanation:
The distances must be expressed in the same uni.
Let's express the distance in meters.
We know that Dory lives 2.5 miles from school.
Since:

The distance in kilometers is:

Since 
The distance in meters is:

Jim lives 3.2 kilometers from school. The distance in meters is:

Chris lives 3,000 yards from school.
Since:

The distance in meters is:

Therefore, the order of the students from closest to farthest from school is:
