In the standard xy-coordinate plane, the xy-pairs (0, 2) and (2, 0) define a line, and the xy-pairs (-2, -1) and (2, 1) define another line. At which of the following points do the two lines intersect?
(A) [43,23]
(B) [32,43]
(C) [−12,32]
(D) [34,−23]
(E) [−34,−23]

I don't know if it is the best methods, but it surely gets you to the right answer. First, you find the slope of both lines with the formula y2-y1/x2-x1. Then you find the Y-intercept of both lines. Finally, you have two equations in this format y = ax + b and you put them equal and find x = 4/3 then you plug x into one of the two-equation and find y = 2/3

Yes, It might be. But plotting these point on number line can give you answer fastly. Try it once.
