Which set of ordered pairs has the same slope as the given set: (2,9) (1,12)?
Irina-Kira [14]

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;

\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.

Alina [70]

This question is incomplete because it lacks the diagram showing the leaf and stem plots

Find attached to this answer the diagram showing the Stem and leaf plots

Answer:

Only one Zoo has exactly 42 lizards

Step-by-step explanation:

If you check out the attached diagram , you will observe that there is a separation using a vertical line

In the diagram also we have been provided with a key which was explained as :

2|0 = 20 lizards

On the left hand side, we have number ranging from 0 - 6 arranged in a vertical form. On the right hand side we almost have numbers that are arranged in front of each number horizontally

Let me further explain the attached diagram

It is important to note that the numbers arranged vertically on the left are in the units of tens. Hence, using the given key :2l0

0|

1|

2| 0 6 8 8 8

This means , we have 20 lizards in one zoo, 26 lizards in one zoo, 28 lizards in 3 zoos

3| 0 2 6 6 7 8

30 lizards in one zoo, 32 lizards in one zoo, 36 lizards in 2 zoos , 37 lizards in one zoo and 38 lizards in one zoo

4| 1 2 6 6

We have 41 lizards in one zoo, 42 lizards in one zoo, and 46 lizards in two zoos

5l

6|

Based on the explanation given above, we can see that only one Zoo has exactly 42 lizards
