What is y=2x+6 written using the standard form of the equation of a line?

Explanation:
"Standard form" of a linear equation is
Ax+By=C
with integer constant values for A,B, and C and ${\displaystyle A\ge 0}$
y=2x+6 can be converted into this form
subtract 2x from both sides
-2x+y=6
multiply both sides by (-1)
2x-y=-6
Standard form: 2x-y=-6
