IMPORTANT

When entering answers, only enter spaces between words. If you are entering an answer for an algebraic rule, ordered pairs/coordinates, or any numbers enter your response with no spaces.

Use parentheses where appropriate!

Examples:

Rule: (2x,2y)

Ordered Pairs/Coordinates: (-1,2)

There are no spaces between any characters.
