Question

Points V, W, X, Y, and Z are graphed on a number line. The coordinate of point V is 3. What points are at a distance of 7 units from point V? Choose all answers that are correct. A. W = –7 B. X = –4 C. Y = 4 D. Z = 10

Answer 1

Because we are only referring to a number line, it is known that the distance between points are the absolute values of the differences between the numbers. From the given choices, B. X = -4 as the distance between 3 and -4 is equal to 7. Similarly, the distance between Z = 10 from V is also 7. The answers are B and D.
