If x = − 4, which number line shows the value of |x|? a number line is shown from negative 6 to positive 6 with increments of 1. all the numbers are labeled on the number line. a dot is shown on a point at 4 tick marks to the left of 0. above the number line, a bracket is shown extending from a point at 4 tick marks to the left of zero to 0. a horizontal line is shown between the brackets, and 4 is written on the line. a number line is shown from negative 6 to positive 6 with increments of 1. all the numbers are labeled on the number line. a dot is shown on a point at 4 tick marks to the left of 0. above the number line, a bracket is shown extending from a point at 4 tick marks to the left of zero to 0. a horizontal line is shown between the brackets, and negative 4 is written on the line. a number line is shown from negative 6 to positive 6 with increments of 1. all the numbers are labeled on the number line. a dot is shown on a point at 4 tick marks to the left of 0. above the number line, a bracket is shown extending from a point at 4 tick marks to the left of zero to a point at 4 tick marks to the right of zero. a horizontal line is shown between the brackets, and 4 is written on the line. a number line is shown from negative 6 to positive 6 with increments of 1. all the numbers are labeled on the number line. a dot is shown on a point at 4 tick marks to the left of 0. above the number line, a bracket is shown extending from a point at 4 tick marks to the left of zero to a point at 4 tick marks to the right of zero. a horizontal line is shown between the brackets, and negative 4 is written on the line.
