<span>5x-6y=-15
5x+6y=12
---------------add
10x = -3
x = -3/10
x = -0.3
</span>5x+6y=12
5(-0.3) + 6y = 12
6y = 12 + 1.5
6y = 13.5
y = 13.5 / 6
y = 2.25
One pair of opposite sides both parallel and congruent implies a parallelogram.
Your going to have to draw it out,but just look for the number on your number line and put a point above the number.
