Answer:
<u>plotting x = 2 </u>
see the x- axis look for the point x = 2(<em>on</em><em> </em><em>right</em><em> </em><em>s</em><em>i</em><em>d</em><em>e</em><em> </em><em>of</em><em> </em><em>the origin</em> ). Mark that point and draw a straight line parallel to the y- axis.
This is the graph of x = 2
<u>plotting y = -4 </u>
see the y- axis and then look for the point y= -4 <em>(</em><em>that</em><em> </em><em>must</em><em> </em><em>be</em><em> </em><em>4</em><em> </em><em>units</em><em> </em><em>below</em><em> </em><em>the</em><em> </em><em>origin</em><em>)</em><em>.</em><em> </em>Mark that point and draw a straight line parallel to the x- axis.
This is the graph of y = -4
we see that, the graph x = 2 is parallel to the y-axis whereas the graph y = -4 is parallel to the x- axis.
