Horizontal
Lines The equation means that the
ycoordinate is always 2. This means that it is a horizontal line passing
through the coordinate The graph below shows a couple of examples of horizontal
lines graphically


Vertical
Lines The equation means that the xcoordinate
is always 2. This means that it is a vertical line passing through the
coordinate The graph below shows a couple of examples of vertical
lines graphically


KEY SUMMARY: ·
Equations
of the form are vertical
lines ·
Equations
of the form are horizontal
lines 
An
example of a geometrical reflection
These two shapes are REFLECTIONS in the line They are MIRROR IMAGES Each corresponding point is the same distance from
the mirror line
