Question

Point X is at 2 on a number line, and point Y id at 7. what is XY?

Answer 1

`\text{length XY = 5 units}`

Here, we want to get the distance XY

All we have to do is to subtract the points from each other

Mathematically, we have this as;

`\begin{gathered} XY\text{ = 7-2} \\ XY\text{ = 5} \end{gathered}`
