प्रश्न
Write an equation representing a pair of lines through the point (a, b) and parallel to the coordinate axes.
उत्तर
The lines passing through (a, b) and parallel to the x-axis and y-axis are y = b and x = a, respectively.
Therefore, their combined equation is given below:
(x \[-\] a)(y \[-\] b) = 0
