Ans.1)  The given equation is 3x-8y=-4

We have 4 options.Lets check them one by one.

1st option:(0,0.5)

Plug in these values into the equation.

3  0 - 8  0.5 = 0-4=-4.

Hence these values satisfy the equation.

2nd option:(4,1)

Now plug in these values.

3  4 - 8  1=12-8=4

Hence this option is not correct.

3rd option:(2,0.75)

Now plug in these values.

3  2 - 8  0.75=6-6=0

Hence this option is incorrect.

4th option:(2,4)

Now plug in these values.

3  2 - 8  4=6-32=-26

Hence this value is also incorrect.

So the domain is (0,0.5).
