#x =# a number is always a vertical line, passing through the #x#-axis at that value of #x#

Explanation:

You could draw the graph by plotting points first. In this case, #x# is always 4, regardless of the #y#-value.

Possible points could be (4;-5), (4;-2), (4;0), (4;7) etc.

Plotting the points will give you a vertical line passing through the #x#-axis at 4.

Vertical lines only have an #x#-intercept. Note that the #y#-axis is also a vertical line, crossing the #x#-axis at 0. The equation of the #y#-axis is #x = 0#
