Question

what is the length of $overline{cb}$ on the number line?
a -3
b -2
c 1
d 3

Explanation:

Step1: Identify coordinates of points

Point C (labeled A in the diagram) is at $-3$, point B is at $-2$.

Step2: Calculate distance (absolute difference)

Length = $|-2 - (-3)| = |-2 + 3| = |1|$

Step3: Simplify absolute value

$|1| = 1$

Answer:

C. 1
