a number line is shown. which expression represents the distance between the two points, x and y, on the number line? a. -4 - 3 b. -4 + 3 c. |-4 - 3| d. |-4 + 3|
Answer
Explanation:
Step1: Recall distance formula on number - line
The distance between two points (a) and (b) on a number - line is given by (|a - b|) or (|b - a|). Here, (a=-4) (co - ordinate of point (X)) and (b = 3) (co - ordinate of point (Y)). The distance (d=| - 4-3|) or (|3-( - 4)|=|3 + 4|).
Answer:
C. (|-4 - 3|)
