Question

MEDALL
is this right?

Answer 1

Not quite. Remember, it is (x (horizontal), y (vertical)

Answer 2

(-4,2) means x = -4, y = 2
every point is of the form (x,y)

Answer 3

x tells you how to move horizontally (left and right)
y tells you how to move vertically (up and down)

Answer 4

its a?

Answer 5

yep!

Answer 6

yes x = -4 means you move 4 units to the left
y = 2 means you move 2 units up

you always start at the origin (where the x and y axis cross)

Answer 7

Point a is correct, not point c

Answer 8

is this correct ? @thefurball

Answer 9

The two points you selected would yield 0, since they were (-9, 9) and (9, -9). Keep trying! Remember that they want you to subtract the negatives.
