The point of intersection of the lines x = 4 and y = -3 is ________.
(4, -3)
(4, 3)
(-4, 3)
(-4, -3)
The line x = 4 is parallel to the y-axis
and the line y = -3 is parallel to the x-axis
Hence the lines intersect at P(4, -3)
Find the equation of straight line joining the point of intersection of 3x-y+9 = 0 and 2y +x -4 = 0 and the point of intersection of 2x+y = 4 and 2y = x +3.
