Question 1043165
<pre><b>{{{drawing(400,400,-7,7,-7,7,
locate(-2-2,1+.6,"A(-2,1)"),
locate(0-1,0+.6,"O(0,0)"),
locate(4.1,4+.6,"B(4,4)"),
grid(1), circle(-2,1,.1),circle(4,4,.1), circle(0,0,.1),
green(line(0,0,-2,0),line(-2,0,-2,1)),
red(line(-2,1,0,0),line(0,0,4,4)) )}}}

To get from O to A, we go LEFT 2 and UP 1.
See the green lines above.

Therefore to get from B to E, we do the same.
Going LEFT 2 and UP 1 from B, puts us here:

{{{drawing(400,400,-7,7,-7,7,
locate(-2-2,1+.6,"A(-2,1)"),
locate(0-1,0+.6,"O(0,0)"),
locate(4.1,4+.6,"B(4,4)"),
grid(1), circle(-2,1,.1),circle(4,4,.1), circle(0,0,.1),
green(circle(2,5,.1),line(4,4,2,4),line(2,4,2,5),locate(2,5+.6,"E(2,5)")),
green(line(0,0,-2,0),line(-2,0,-2,1)),
red(line(-2,1,0,0),line(0,0,4,4)) )}}} 

and we see that the point is E(2,5), so we
finish drawing parallelogram AOBE:

{{{drawing(400,400,-7,7,-7,7,
locate(-2-2,1+.6,"A(-2,1)"),
locate(0-1,0+.6,"O(0,0)"),
locate(4.1,4+.6,"B(4,4)"),
grid(1), circle(-2,1,.1),circle(4,4,.1), circle(0,0,.1),
locate(2,5+.6,"E(2,5)"), circle(2,5,.1),
red(line(-2,1,0,0),line(0,0,4,4),line(4,4,2,5),line(2,5,-2,1)) )}}}
