+33661 A linear equation is one in which the dependent variable (y, say) depends directly on the independent variable (x) raised to the power 1, but not on powers of the independent variable other than 1.
For example y = 2x + 3 is a linear equation, but y = 2x2 + 3 isn't. (Note that x is the same thing as x1)
y = 5x - 9 is linear, but y = √x -9 isn't.
