graphs of each of these on the xy-plane.
The line in (A) contains both the given points, but all the points to the left of (0, 4) are
closer to that point and all those to the right of (8, 0) are closer to it. So eliminate (A).
Many points on line (B) are also clearly closer to one or the other of the given points, so
eliminate (B). Line (C) appears to be perpendicular to the line formed by the two given
points, and this is in fact what will make all the points on a line equidistant from 2 given
points. Therefore, the correct answer is (C).

Get rid of the fractions in the first equation by multiplying the entire equation by 6, to get 2p
+ 3q = 6. Whenever there are two equations with the same two variables, they can be
