Since y is the variable, x is considered here as a constant.
Then :
-x + 3y = -6
we add x in both left side and right side of the equation :
-x + x + 3y = -6 + x
3y = -6 + x
Then we divide both side by three :
3y / 3 = (-6+x) /3
y = (-6+x)/3
y = -6/3 + x/3
y= -2 + x/3

Answer:
C
Step-by-step explanation:
A proportional relationship exists where the outputs and inputs have a constant of proportionality. This is a ratio of y/x that is the same between all x and y values in a table.
a. x: 0,1,2 y:2,5,8
2/0 = 0, 5/1 = 5 not proportional
b. x: 0,1,2 y:0,1,4
1/1 = 1, 4/2 = 2 not proportional
c. x: 0,1,2 y:0,3,6
3/1 = 3, 6/2 = 3 YES proportional
d. x 0,1,2 y:2,3,7
2/1 = 2, 3/2 = 1.5 not proportional
