• 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.
