In geometry, it is important to understand the concept of slope. Slope is the measure of how steep a line is. It is calculated by finding the change in the y-coordinate value divided by the change in the x-coordinate value. In this article, we will discuss how to calculate the slope of line MN, which contains points M (1, 3) and N (5, 0).

## Calculating the Slope of Line MN

The first step to calculate the slope of line MN is to find the change in the y-coordinate value. This is done by subtracting the y-coordinate of point M (3) from the y-coordinate of point N (0). This gives us a difference of -3.

The second step is to find the change in the x-coordinate value. This is done by subtracting the x-coordinate of point M (1) from the x-coordinate of point N (5). This gives us a difference of 4.

## Finding the Slope of Line MN

The last step is to divide the change in the y-coordinate value by the change in the x-coordinate value. This gives us a slope of -3/4. Therefore, the slope of line MN is -3/4.

In conclusion, calculating the slope of line MN is a simple process that requires the calculation of the change in the y-coordinate and x-coordinate values and dividing the results. Once this is done, the slope of line MN can easily be determined.
