Answer
Quadrant I and Quadrant III
If a point has a y-coordinate of zero, which axis does it lie on?
Try plotting the point (-2, 0).
The x-axis
Do the points (-8, -1), (-6, 1), (-4, 3) and (0, 7) lie in a straight line?
If you don't know, try plotting these points.
Yep, they do.
What type of quadrilateral do the points (-3, 1), (4, 1), (2, -2) and (-5, -2) form?
Have you bothered to graph them yet?
They form a parallelogram.
