Question

If you are looking at the rise over the run on a curve you are determining

run of a curve.

slope of a curve.

Answer 1

In this question term rise refers to the change in the distance of vertical axis ; whereas run refers to the change in the distance of horizontal axis on a graph .

Rise Over Run refers to the Slope of a curve.

To find the Slope of a curve we find the ratio of the change in the units of vertical axis to the change in the units of horizontal axis.

In the diagram below, we see two points on the curve in which the vertical axis is represented by marginal cost and the horizontal axis is represented by the quantity

Now we can see in the diagram two points .
On the first point value on the vertical axis = 3; the value on the horizontal axis equals 2
On the second point the value on the vertical axis = 5 and the value on the horizontal Axis equals 4

To find the slope we use the following formula:

Change in the units on Vertical axis divided by change in the units on Horizontal axis

Value on the horizontal axis Increases from 2 to 4
So the change in horizontal horizontal axis = 2

Values on the vertical axis increases from 3 to 5,so the change in vertical axis equals 2.

The slope is equals to = 2 / 2
Slope = 1
