Answer:

The correct options are b and c.

Step-by-step explanation:

The given equation is

[tex]y=\frac{2}{3}x-4[/tex]

The slope intercept form of a linear equation is

[tex]y=mx+b[/tex]

In option a,

[tex]3x-2y=4[/tex]

[tex]3x-4=2y[/tex]

Divide both sides by 2.

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

Therefore option a is incorrect.

Similarly rewrite all equations in their slope intercept form.

In option b,

[tex]2x-3y=12[/tex]

[tex]2x-12=3y[/tex]

[tex]\frac{2}{3}x-4=y[/tex]

Therefore option b is correct.

In option c,

[tex]-4(2x-3y)=-4(12)[/tex]

[tex]2x-3y=12[/tex]

[tex]2x-12=3y[/tex]

[tex]\frac{2}{3}x-4=y[/tex]

Therefore option c is correct.

In option d,

[tex]2(x+6)=3y[/tex]

[tex]2x+12=3y[/tex]

[tex]\frac{2}{3}x+4=y[/tex]

Therefore option d is incorrect.

In option e,

[tex]2x-3y=4[/tex]

[tex]2x-4=3y[/tex]

[tex]\frac{2}{3}x-\frac{4}{3}=y[/tex]

Therefore option e is incorrect.
