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).
