• The following formula can be used to find the slope of a line:

These points are on the line:

Given the following points:

Then, you can set up that:

Therefore, substituting values into the formula and evaluating, you get:

• As you can notice, the slope is negative. Therefore, you can determine that it is decreasing.
Therefore, the answers are:
• Slope of the line:

• It is decreasing.
