Question

What is y-8=3(x+1) written in standard form

Answer 1

Standard form of a linear equation is Ax + By = C, where A, B, C are constants.

So,
y-8 = 3(x+1)
y-8 = 3x + 3

substract 3 from both sides,
y-8-3 = 3x+3-3
y-11 = 3x

substract y from both sides,
y-y-11 = 3x-y
-11 = 3x-y

So, the standard form is 3x-y = -11
