The Total solution for NCERT class 6-12
Give the geometric representations of 2x + 9 = 0 as anequation
(1) in one variable
(2) in two variables
(1)In one variable, 2x + 9 = 0 represents a point as shown in the following figure.
(2) In two variables, 2x + 9 = 0 represents a straight linepassing through point(−4.5, 0) and parallel to y-axis. It is a collection of all pointsof the plane, having their x-coordinate as 4.5.
