One way to look at absolute value is to think of the absolute value of a number as its distance from zero on a number line. For example, 161 = 6 and 1-61 = 6 because both 6 and 6 are exactly 6 units from zero on a number line. You can, therefore, think of the equation such as x1 = 5 as the question, “What numbers are exactly five units from zero on the number line?” Thus, the solutions are 5 and -5. Draw a number line to show the solutions to the following equations. ( (multiple choice)

a. 1.1 = 3
b. 1x1 = 0
c. 1*1 + 2 = 6
d. 31.51 = 15
e. Ix-51= 2
f. 1x + 31 = 7
