Answer
Let cost of carton represent y and let number of cartons represent x
Equation: y=3x
Table:
X | Y
(0 , 0)
(1 , 3)
(2 , 6)
(3 , 9)
(4 , 12)
Work Step by Step
We can model the relationship through the equation y=3x because since each carton cost $3, the slope becomes 3 and since no other items are bought, the y-intercept become (0,0), thus forming the equation.
The table can be formed by plugging in any value for x and then solving for y. For example:
(Plugging in 2 for x)
y=3x
y=3(2)
y=6
This forms the ordered pair (2,6).
