Worksheet
Horizontal and vertical lines
1

State whether the graphs of the following lines are horizontal or vertical:

a

y = 2

b

x = - 4

c

y = 3

d

x = 17

e

y = 0

f

x = 0

g

y -\dfrac{1}{2} = 0

h

\dfrac{4}{7} = x

2

The table shows some points on the line with equation x = 0.

Does the line x = 0 represent the y-axis or x-axis?
