The combinations of sizes allow him to empty the bathtub in exactly four trips is a 5-liter bucket with the 3-liter bucket twice, a 3-liter bucket and the 4-liter bucket.
The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Paul's bathtub is clogged. He has to empty 30 liters of water by hand.
Paul has a 3-liter, a 4-liter, and a 5-liter bucket.
If Paul carries two buckets each trip, we need to find the combinations of sizes that allow him to empty the bathtub in exactly four trips.
5 and 3 = 8 liters ,
5 and 4 = 9 liters,
3 and 4 = 7 liters.
8 + 7 + 8 + 7 = 30 liters,
So,
He can take the 5-liter bucket with the 3-liter bucket twice, and then he can use the 3-liter bucket and the 4-liter bucket twice.

y=2/3x+3
y=__/__x+5
equation: y = x + 5
We start the function table at the y-intercept, which is listed as 5 in this equation. Since this is at the y-intercept, the x-value would be 0.
(0,5)
Next you use the slope to find the next x and y values. The slope is x, or 1. So whenever you move up a 1 x-value, you'll also move up 1 y-value.
(1,6)
A thing to consider is that you can just plug in any x-value you want and then you can solve the equation to get the y-value that goes with it.
Example:
y = x + 5 ---> y = 2 + 5 ---> y = 7
By doing this, you can easily get all of the functions in the table.(

plug in any numbers for x and solve for y. normally I recommend you to do -2,-1,0,1,2 for the x-values
