Lines parallel to x-axis

Equation of x-axis is

y = 0

 

Equation of lines which are parallel to x-axis is

y = k

where k is a constant

 

Let us check an example

y = 2

 

Drawing y = 2 in graph

 

Since y = 2 for all values of x

Points which satisfy the equation is

x

0

1

2

–1

y

Hence, y = 2 is  line which is parallel to x axis

 

Lines parallel to y-axis

Equation of y-axis is

x = 0

Equation of lines which are parallel to y-axis is

x = k

where k is a constant

Let us check an example

x = 1

Drawing x = 1 in graph

Since x = 1 for all values of y

Points which satisfy the equation is

x

1

Equation of line parallel to x-axis and y-axis - Part 2

 

Hence, x = 1 is  line which is parallel to x axis
