Answer: B. (-3, 3.25)
Step-by-step explanation: Imagine that the line is divided into 4 segments. (3:1) Since A is at the upper right end of the line, go 3 segments down and left from A. That puts the x value at -3.
If you graph the line, it is evident that the y-value is at 3.25.
(It may be possible to use the Pythagorean Theorem to compute the lengths of line segments-- but this is a multiple-choice question!)
