How do you write ##y=2x+1## in standard form?

The standard form of a linear equation is ##ax + by = c##

We can transpose ##2x## to the left hand side to get

## y - 2x = 1##

##-> -2x + y = 1##

Multiplying both sides with ##-1## gives us

##color(green)(2x - y = -1## is the Standard form of ##y=2x+1##
