How do you plot the ordered pairs on the rectangular coordinate system (2, 1), (-3, 5), and (7, -3)?

Answer 1

See explanation

Complying with convention, if we put them in order using the #x# values we have:

#(-3,5)"; "(2,1)"; "(7,-3)#

On a graph you always read left to right on the x-axis. This is particularly important when calculating gradients (slope).

To plot the ordered pairs (2, 1), (-3, 5), and (7, -3) on the rectangular coordinate system:

For the point (2, 1): Move 2 units to the right along the x-axis, then move 1 unit up along the y-axis and mark the point.
For the point (-3, 5): Move 3 units to the left along the x-axis, then move 5 units up along the y-axis and mark the point.
For the point (7, -3): Move 7 units to the right along the x-axis, then move 3 units down along the y-axis and mark the point.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
