Points R, S, and T are plotted on a number line. The coordinate of point R is –6. Points S and T are the same distance from point R.
What could be the coordinates of S and T?
A.
S = 0, T = 6
B.
S = –4, T = –2
C.
S = –9, T = –12
D.
S = –10, T = –2

Best ResponseYou've already chosen the best response.1They want RS to be equal to RT. That's what it means for R to be the same distance from S as it is from T. Is that true for option A here?

Best ResponseYou've already chosen the best response.1The distance between R and S = 6. From 6 to 0 is a distance of 6. But from R to S, and then S to T, that is a distance of 6 + 6. So no. They are not equal. Part A is not the correct option.

Best ResponseYou've already chosen the best response.1Instead of graphing, it might just be easier to set this up as a subtraction problem :) \(\large\rm R=6\) For option B: \(\large\rm S=2,\quad T=4\) So then subtracting S from R, or R from S, tells us the distance between them. \(\large\rm RS=2(6)=4\) \(\large\rm RT=4(6)=2\) Again these lengths are not equal.

Best ResponseYou've already chosen the best response.1Try option D: \(\large\rm RS=6(10)=?\) \(\large\rm RT=2(6)=?\)

Best ResponseYou've already chosen the best response.1Near the top right, you should see a little green text that says: \[\rm \color{green}{\triangle\text{ 172 members online}}\]Something like that. It brings you to the ... lobby or whatever :d
