Question

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

Answer 1

The standard form of an equation of a line is written as:

Ax + By = C 

where A, B and C are constants.

y = –2/3x + 7 
2/3x + y = 7
(2/3x + y = 7)3
2x + 3y = 21

Therefore the correct answer is the first option.
