Question

Which set of ordered pairs has the same slope as the given set: (2,9) (1,12)?

Answer 1

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;

$\mathbf{Slope(m) = \dfrac{\Delta y}{ \Delta x}}$

$\mathbf{Slope(m) = \dfrac{y_2-y_1}{x_2-x_1} }$

Here:

• x_1 = 2
• y_1 = 9
• x_2 = 1
• y_2 = 12

$\mathbf{Slope(m) = \dfrac{12-9}{1-2} }$

$\mathbf{Slope(m) = \dfrac{3}{-1} }$

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.
