Question

Which of the following coordinates exists on the line y=2x-4 ?

A. (2,-4)
B. (-1,2)
C. (-3,-5)
D. (1,-2)

THANK YOU!!

Answer 1

Any ideas?

Answer 2

no haha :/

Answer 3

What does it mean for coordinates to exist on a line?

Answer 4

Recall given an ordered pair such as $$\huge(1,-2)$$ the x-coordinate is 1 and the y-coordinate is -2.

Answer 5

Do those^ values satisfy the equation: $$\Huge y=2x-4$$ if the answer is "yes" then they do exist on the line.

If the answer is no then they do not exist on the line.
