Question

y=1/2x - 3 in standard form using integers?

Answer 1

standard form : Ax + By = C

first you need to multiply everything by 2 to get rid of the fraction because an integer is a whole number, not a fraction.
y = 1/2x - 3
(2)y = (2)1/2x - (2)3
2y = x - 6
Now you want to move the x to the other side and to do this you need to subtract x from both sides.
2y - x = x - x - 6 (combine like terms)
2y - x = 6

you want it in standard form Ax + By = C
-x + 2y = 6
You do not want the x to be a negative so multiply the equation by a -1
(-1)-x + (-1)2y = (-1)6
x + (- 2y) = -6 <----standard form
