What is an equation of the the line that passes through the point (3,6)and is parallel to the line 4x-3y=21
\(\text{One simple way to do this is to change the constant on the right hand side until $(3,6)$ solves the equation}\\ 4(3)-3(6) = 12-18 = -6\\ 4x-3y=-6\\ \text{is parallel to $4x-3y=21$ and passes through $(3,6)$}\)
