Chapter 1: Q17. (page 31)

Refer to a number line that is not pictured here. Point $A$ has coordinate 2 and point $B$ has coordinate 5.
What is the coordinate of the midpoint of $A B$ ?

Short Answer

Expert verified

The required coordinate is $3.5$ .

Step by step solution

Step 1. Make the number line.

Make a number line that consists of two points $A$ and $B$ according to the provided information and a number 0 between $A$ and $B$ .

Step 2. Form the equation required to calculate the coordinate.

The midpoint of given segment $A B$ can be calculated by half of the addition between $A$ and role="math" localid="1649152325879" $B$ so make an equation according to this.

$A B = \frac{A + B}{2}$

Step 3. Calculate the required coordinate.

Substitute the given values of $A$ and $B$ into the obtained equation and calculate the required coordinate.

$A B = \frac{2 + 5}{2} = \frac{7}{2} = 3.5$
