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

-- You've told me that there are 5 houses on a map, and 

-- you've told me the address of one house.

-- You won't show me the map, but

-- you're asking me which houses are 7 miles from that one.

Can you see what's missing here ?

You haven't told me a thing about any of the other points/houses.
I don't even know if any of the others are in the same city as ' V ' is,
or even on the same planet !

So,

We need to find all points that are 7 units from point V.  We can just test which ones are 7 units away by taking the absolute value of the different between their coordinates.

A. W = -7
|-7 - 3| = |-10| ≠ 7

B. X = -4
|-4 - 3| = |-7| = 7

C. Y = 4
|4 - 3| = |1| ≠ 7

D. Z = 10
|10 - 3| = |7| = 7

Points X and Z are 7 units from point V; in fact, points X and Z are the only points at a distance of 7 units from point V.
