ONLY ANSWER IF YOU KNOW 100% THAT YOUR'E CORRECT
Goryan [66]

The value that represents the distance between -10 and 5 on a number line is A)  |-15|

<h3>How to solve for the value</h3>

We have the value at the negative end to be = -10, while the given value that we have on the positive end is given as 5

To get the value we would have to solve it as

-10-(+5)

= -10 - 5

= -15

Hence we can conclude that the distance between the values is given as |-15|

Which equation is represented on the graph?
Westkost [7]

[ Answer ]

\boxed{Y \ = \ X \ + \ 2}

[ Explanation ]

Y = X + 2 is saying that Y, is the X dot + 2.

When the X dot is on 0, we have to add 2 to get to where the Y dot is. X (0) + 2 = 2. That is where the Y dot is.

X (2) + 2 = 4. 4 is where the Y dot is,

Once you keep adding the X dots to 2, you will get the Y dots. That is why the equation is Y = X + 2. In order to get to Y, you need to add 2 to the X dot.
