Question

what is the length of $overline{da}$ on the number line?
a -5
b -3
c 2
d 5

Explanation:

Step1: Identify coordinates of D and A

From the number line: $D = 2$, $A = -3$

Step2: Calculate length of $\overline{DA}$

Length is absolute difference: $|D - A| = |2 - (-3)|$

Step3: Simplify the expression

$|2 + 3| = |5| = 5$

Answer:

D. 5
