How many solutions of the equation 2x + 1 = x – 3 are there on the Cartesian plane? -Maths 9th
by

1 Answer

Answer :

2x + 1 = x – 3 2x-x = -3-1 ∴ x = – 4 ………..(i) and it can be written as 1.x + 0. y = – 4 …………..(ii) (i) Number line represent the all real values of x on the X-axis. Therefore, x = – 4 is exactly one point which lies on the number line. (ii) Whereas the equation x + 4 = 0 represent a straight line parallel to Y-axis and infinitely many points lie on a line in the cartesian plane.
