coordinates and variations

[Deja Vu]

(xy) (2x,2y) (-2x,-2y)
(-4,-2)
(-2,-2)
(-2,-3)
(-1, 1)

How do I solve for 2x,2y and for -2x,-2y???? This is an assignment for coordinates and variations

 (x, y)            (2x, 2y)              (-2x, -2y)

(-4, -2)              ?                      ?

(-2, -2)              ?                      ?

(-2, -3)              ?                      ?

(-1, 1)               ?                      ?

We cannot use the spacebar at this web site to align columns because this web site strips out extra spaces.

Use the [ code ] and [ /code ] tags with the Preview button to "draw" stuff using extra spaces, as I did above.

You did not type the assignment, so I'm trying to guess what you're supposed to do from the chart that you tried to post.

You asked, "How do I solve for 2x?".

We use the word "solve" when talking about equations. You've posted no equations; therefore, there is nothing to "solve".

The expression 2x means "two times x".

The expression -2x means "negative two times x".

Therefore, if you're given an x-coordinate of -1, then you find 2x and -2x by replacing the symbol x with -1, followed by doing those multiplications.

(2)(-1) = -2

Therefore, 2x = -2 when x is -1.

(-2)(-1) = 2

Therefore, -2x = 2 when x is -1.

Do the same with the y-coordinates.

Please show your work, if you would like more help with this assignment.

If I've guessed wrongly about what you're supposed to do with these four given points, then please let me know.
