Question

find the distance between i and j on the number line below.
(number line with i at -4 and j at 5, and a box for distance input with reset and close buttons)

Explanation:

Step1: Identify coordinates of I and J

Point I is at -4, point J is at 5.

Step2: Calculate distance using formula

Distance between two points \( x_1 \) and \( x_2 \) on number line is \( |x_2 - x_1| \). So \( |5 - (-4)| = |5 + 4| = 9 \).

Answer:

9
