Write y = –2/3x + 7 in standard form using integers.
2x + 3y = 21
3x – 2y = 21
–2x – 3y = 21
–2x + 3y = 7

Question

Write y = –2/3x + 7 in standard form using integers.  
2x + 3y = 21
3x – 2y = 21
–2x – 3y = 21
–2x + 3y = 7

anonymous · Answer

The standard form looks like:  Ax + By = C

anonymous · Answer

So, a good first step would be to get your initial equation in a form that doesn't have any fractions...

y = –2/3x + 7

Try multiplying everything by 3.... what is your new equation then?

Is the answer to the problem A?

anonymous · Answer

d

anonymous · Answer

When I solve it, I get:

y = –2/3x + 7

3y = -2x + 21    (Multiply through by 3)

2x + 31 = 21      (move 2x to the left side)

That matches answer A...

oops, typo above.... last line should have been 2x + 3y = 21

not sure why it typed "31" where I meant "3y".
