# Draw the graph of each of the following equations:

(i) x = 5

(ii) y = -2

(iii) x + 6 = 0

(iv) x + 7 = 0

(v) y = 0

(vi) x = 0

Answer :

(i) The given equation is x = 5

A line requires minimum of two points to be plot.

Thus we get the following table:

Plot points A (5,1) and B (5,-1) on the graph paper.

Join AB.

The line AB is the required graph.

(ii) The given equation is y = -2

A line requires minimum of two points to be plot.

Thus we get the following table:

Plot points A(1,-2) and B(2,-2) on the graph paper.

Join AB.

The line AB is the required graph

(iii) The given equation is x + 6 = 0, which means x = -6

A line requires minimum of two points to be plot.

Thus we get the following table:

Plot points A (-6,1) and B (-6,-1) on the graph paper.

Join AB.

The line AB is the required graph

(iv) The given equation is x + 7 = 0, which means x = -7

A line requires minimum of two points to be plot.

Thus we get the following table:

Plot points A (-7,1) and B (-7,-1) on the graph paper.

Join AB.

The line AB is the required graph

(v) Y =0 represents the x – axis

(vi) x = 0 represents y – axis
