Question 414595: kindly help me with this question
a) x -2, -1, 0, 1, 2
y 3, 5, 7, 9, 13
b) x -1, 9, 1, 2, 3
y 2, 0, -2, -4, -6
c) x 1, 0, 1, 2, 3
y -.08, 0, 0.8, 1.6, 2.4
d) x -2, -1, 0, 1, 2
y -0.2, 0.4, 1, 1.6, 2.2
please examine the tables where x has both negative and positive values. In what way does a table of values that represents a direct variation differ from one that does not?

You can put this solution on YOUR website! Note: Direct variation implies that y-values will have consistent
difference if the x-values have a consistent difference.
-------
a) x -2, -1, 0, 1, 2
y 3, 5, 7, 9, 13
No consistent y-diff.
-----------------------------
b) x -1, 0, 1, 2, 3
y 2, 0, -2, -4, -6
Yes ; diff = -2
-----------------------------
c) x 1, 0, 1, 2, 3
y -.08, 0, 0.8, 1.6, 2.4
Yes ; diff = +0.8
----------------------------------
d) x -2, -1, 0, 1, 2
y -0.2, 0.4, 1, 1.6, 2.2
Yes ; diff = +0.6
----------------------------------
