Q1 of 39 Page 146

Give the graphical representation of the following equation.

a) On the number line and


b) On the Cartesian plane


y + 3 = 0

We are given, y + 3 = 0


We get, y = -3


The representation of the solution on the number line, when equation is treated as an equation in one variable.



The representation of the solution on the Cartesian plane, it is parallel to y axis passing through-the point (0,-3) is shown below
