Answer:
one can of tuna is 1.66666666667$
Step-by-step explanation:
4x-3y=-9
The first step is to isolate your y value.
Subtract 4x from both sides to get
-3y=-4x-9
Then, divide your whole equation by -3. This gives you y=4/3+3
To graph, plot (0, 3), or three on your y-axis to get your y-intercept.
For your slope, use the rise/run (go up 4, across 3)
You should have a positive slope.
Pretty sure you just scale it down 4 times
(Because 20/4=5cm)
i got what he got , If c is cost and X is the item, c=x-.12 or c=x*.88
