My Dad helped me with this.

The slope, equation and number of eggs used for 12 cups of flour is required.

The slope of the equation is [tex]\dfrac{3}{2}[/tex]

This means for 3 cups of flour 2 eggs will be used.

The equation is [tex]y=\dfrac{3}{2}x[/tex]

For 12 cups of flour 8 eggs will be required.

The cup of flour is y

The number of eggs is x

cups of flour is proportional to number of eggs

[tex]y\propto x[/tex]

6 cups of flour for every 4 eggs

[tex]y=kx\\\Rightarrow 6=k4\\\Rightarrow k=\dfrac{6}{4}\\\Rightarrow k=\dfrac{3}{2}[/tex]

The slope of the equation is [tex]\dfrac{3}{2}[/tex]

This means for 3 cups of flour 2 eggs will be used.

The equation is

[tex]y=\dfrac{3}{2}x[/tex]

If 12 cups of flour are used

[tex]12=\dfrac{3}{2}x\\\Rightarrow x=12\times \dfrac{2}{3}=8\ \text{eggs}[/tex]
