Explain how to use a number line to compare two integers

Alex787 [66]

<span>Smaller numbers are to the left and larger numbers are to the right on number line. For example numbers 5 and 9! 5 is to the left of 9 so 5 is smaller than 9 or 9 is larger than 5! So graph the number on a number line to see which is greater or smaller! I hope that helps</span><span /><span>

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.

Choose the system of equations which matches the following graph:

Kipish [7]

3x - 2y = 8

- 2y = 8 - 3x

2y = 3x - 8

y = 1.5x - 4

This is the red graph

6x - 4y = 20
