y -4 -6 -10 -12
(D) x 2 4 6 8
y 2 3 4 5
18. Which equation is true for all x- and y- values in the table below?
x y
1 7
2 14
3 21
4 28
(A) y=x+7
(B) y=x-7
(C) y=x/7
(D) y=7x***
17 answers
(B) (-5, -49), (2, -22), (3, 23)***
x = -5 , y = -45 - 4 = -49
x = 2 , y = 18 -14 = 14 TILT!!!!!
(B) x 1 2 5 8 ***
y -2 0 6 12
well -2/1 = -2
0/1 = 0
what is proportional about that ?
