The slope(m) of the given set is -3.
<h3>What is the slope of a pair of the ordered set?</h3>The slope(m) of a pair of the given ordered set is the change in the rise over the run. The rise is the y-axis while the run is the x-axis.
Mathematically;
Here:
- x_1 = 2
- y_1 = 9
- x_2 = 1
- y_2 = 12
Slope (m) = -3
Therefore, we can conclude that the slope of the given set is -3. From the given option, kindly find out which of the slope is equivalent to -3.
