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

standard form does not like a minus sign on the x value. That rules out two of your choices. (standard form puts the variables in alphabetical order, so first x then y) I would multiply your original equation by 3: every term on both sides of the = that should get you started.

How do you multiple the 2/3x by 3 with the x there?

3 times (2/3x) = (3/1) times (2/3x) 3 times (2/3x) = (3*2)/(1*3)x 3 times (2/3x) = (6)/(3)x 3 times (2/3x) = 2x
