Linear Equations in Two Variables question bank (Maths)

Write each of the following equations in the form $ax + by + c = 0$ and indicate the values of $a$,$b$ and $c$ in each case:
$(i)$ $2x + 3y = 4.37$
$(ii)$ $x - 4 = \sqrt{3}y$
$(iii)$ $4 = 5x - 3y$
$(iv)$ $2x = y$

Write each of the following as an equation in two variables:
$(i)$ $x = -5$
$(ii)$ $y = 2$
$(iii)$ $2x = 3$
$(iv)$ $5y = 2$
