12.) write y = 1/6 x + 7 in standard form using integers.

–x + 6y = 42

–x + 6y = 7

6x – y = 42

–x – 6y = 42

Option A

-x + 6y = 42 is the standard form

Solution:

Given that we have to write in standard form

The standard form of an equation is Ax + By = C

In this kind of equation, x and y are variables and A, B, and C are integers

Given equation is:

Let us convert the above equation into standard form

Make the denominator same in R.H.S

Solve the above equation

Move 6 from R.H.S to L.H.S

Bring all the terms to one side, leaving only constant on R.H.S

The above equation is of form Ax + By = C

Thus option A is correct
