Evaluate the expression for r = –1. |r − 3| = _____

Substitute value of r: Step 1: Substitute the value of r into the expression. Calculation: |r - 3| = |-1 - 3| Math reasoning: Replace r with -1 in the expression.Simplify expression inside: Step 2: Simplify the expression inside the absolute value. Calculation: |-1 - 3| = |-4| Math reasoning: Adding -1 and -3 gives -4.Calculate absolute value: Step 3: Calculate the absolute value. Calculation: |-4| = 4 Math reasoning: The absolute value of -4 is 4, as it's the distance from zero on the number line.
