Answer:
7
Step-by-step explanation:
The absolute value of a number is its distance from 0. If you plot -7 and 0 using two dots on a number line, those two points will be 7 units apart.
More formally,
If x > 0 (x is positive), |x| = x. The absolute value of a positive number is just the number.
If x < 0 (x is negative), |x| = -x. The absolute value of a negative number is its opposite, which is a positive number.
If x = 0, |x| = 0.
