Give the geometric representations of the following equations

Question:

Give the geometric representations of the following equations

(a) on the number line (b) on the Cartesian plane:

(i) x = 2 

(ii) y + 3 = 0

(iii) y = 3

(iv) 2x + 9 = 0

(v) 3x - 5 = 0

Solution:

(i) We are given, x = 2

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

The representation of the solution on the Cartesian plane, it is a line parallel to y axis passing through-the point (2, 0) is shown below

(ii)  We are given, y + 3 = 0

We get, Y = – 3

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

The representation of the solution on the Cartesian plane, it is a line parallel to x axis passing through the point A(0, –3) is shown below

(iii) we are given. y = 3

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

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

(iv) We are given, 2x + 9 = 0

We get, 2x = - 9

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

The representation of the solution on the Cartesian plane, it is a line parallel to y axis passing through the point (-9/2, 0) is shown below

(v) We are given, 3x - 5 = 0

We get, 3x = 5

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

The representation of the solution on the Cartesian plane, it is a line parallel to y axis passing through-the point (5, 0) is shown below
