Answer :
The slope(m) of the given set is -3.
What is the slope of a pair of the ordered set?
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;
[tex]\mathbf{Slope(m) = \dfrac{\Delta y}{ \Delta x}}[/tex]
[tex]\mathbf{Slope(m) = \dfrac{y_2-y_1}{x_2-x_1} }[/tex]
Here:
- x_1 = 2
- y_1 = 9
- x_2 = 1
- y_2 = 12
[tex]\mathbf{Slope(m) = \dfrac{12-9}{1-2} }[/tex]
[tex]\mathbf{Slope(m) = \dfrac{3}{-1} }[/tex]
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.
