I Think This Is It

A linear equation in two variables doesn't involve any power higher than one for either variable. It has the general form:

Ax + By + C = 0Ax+By+C=0

where A, B and C are constants. It's possible to simplify this to

y = mx + b\text{ where } m = \frac{ −A}{B}y=mx+b where m=

B

−A

and b is the value of y when x = 0. A quadratic equation, on the other hand, involves one of the variables raised to the second power. It has the general form

y = ax^2 + bx + cy=ax

2

+bx+c

Apart from the adding complexity of solving a quadratic equation compared to a linear one, the two equations produce different types of graphs.
