Linear equations are the easiest of all. They do not involve any powers at all. Square roots maybe, but never powers. Linear equations are any equations that are written with a, b, c and so on which are real numbers, either positive or negative. x would be the variable. The basic principles are: if a = b, a - c = b - c, a + c = b + c and ac = bc. Graphs for this type of equations involve one straight line. For y = 2x + 1 as the line increases at y, it increases twice as fast as it increases at x, thus 2x.
