Question 353556
Just plug in points using the x and y values and see if the eqaution is satisfied.
{{{ 2x=6y-4}}}
Try point (2,4)
{{{ 2*2 = 6*4 - 4}}}
{{{4 = 24-4}}}
{{{4 = 20}}} which is not true. So A is not on the line

Try B
(4,2)
{{{2x=6y-4}}}
{{{2*4 = 6*2 - 4}}}
{{{8 = 12 - 4}}}
{{{8 = 8}}} so far so good
Try the next point in B
(-5, -1)
{{{2*(-5) = 6*(-1) - 4}}}
{{{-10 = -6 -4 }}}
{{{-10 = -10}}} still good

Keep doing that for the last point in B
Then also try points in C and D

Get it?
