Question

For a line on a number line with point X at 4 and point Y at 22: 6) What is the midpoint of the line? 7) How long is the line?

Answer 1

Answer:

6) Midpoint = 13

7) The length of the line = 18

Explanations:

On the number line, there are two points:

X = 4, Y = 22

6) The midpoint of the line will be given by the equation:

`\text{Mid point = }\frac{X\text{ + Y}}{2}`
`\begin{gathered} \text{Mid point = }\frac{22\text{ + 4}}{2} \\ \text{Midpoint = }(26)/(2) \\ \text{Midpoint = 13} \end{gathered}`

7) The length of the line will be calculated as:

XY = Y - X

XY = 22 - 4

XY = 18
