Answer:when x=0; y=18
When x=;6 y=0
When x=3; y=9
Explanation:
To complete the table for when x=0, you need to make 'y' subject of the formula.
9x+3y=54
3y=54-9x
Divide both sides by the coefficient of y.
y=(54-9x)÷3
y=18-3x
Therefore, when x=0,
y=18-3(0)
y=18.
When x=3,
y=18-3(3)
y=18-9
y=9
When y=0, you need to make x subject of the formula.
9x+3y=54
9x=54-3y
Divide both sides by 9
x=(54-3y)÷9
x=6-y÷3
When y=0,
x=6-(0)÷3
x=6.
