I think by y = 2/3x + 1, you mean y = (2/3)*x + 1.

So to find the value of y in this case, multiply x with (2/3) and add 1.

Similarly for y = (3/4)x - 2, multiply x with (3/4) and subtract 2 from the result.

I think by y = 2/3x + 1, you mean y = (2/3)*x + 1.

So to find the value of y in this case, multiply x with (2/3) and add 1.

Similarly for y = (3/4)x - 2, multiply x with (3/4) and subtract 2 from the result.

In case you mean y = 2/(3x) +1, you will:

- first have to multiply x with 4
- then divide 2 by the result you get
- and finally add 1

For y = 3/(4x) + 1,

- first multiply x with 4
- divide 3 by the result
- and finally add 1.

In case you mean y =2/(3x+1),

- first multiply x and 3
- add one to the result
- finally divide 2 by what you get after step 2.

Similarly for y =3/(4x - 2),

- first multiply x with 4
- then subtract 2 from it
- and finally divide 3 by the result after step 2.
