One way to do this when the equation is in standard form is to note that the lines of the equations
Ax + By = C1
and
Bx - Ay = C2
are perpendicular. Therefore, a line perpendicular to 5x - 2y = -6 must take the standard form 2x + 5y = C.
Substituting x = 5, y = -4, we get
C = 2(5) + 5(-4) = 10 - 20 = -10.
Thus, 2x + 5y = -10 is correct.
