Let the line p be the perpendicular bisector of A = (24, 7) and B = (-3, 4). Given that AB meets p at C = (x, y), what is 2x - 4y.
+1223 perpendicular bisector passes through midpoint: \((\frac{24-3}{2}, \frac{7+4}{2}) = (21/2, 11/2)\)
The midpoint is the "C" that the problem is talking about, so 2x - 4y = 21 - 22 = -1.
