What is the difference between a linear equation and a quadratic equation?

Answer:

A linear equation when plotted on a graph, is represented by a straight line on the other hand, a quadratic equation is represented by a parabola. First-degree equations or straight-line equations have a uniform rate of change and they are outlined as y = mx + b; m and b being constants. They include only the variables raised to the first power. While quadratic equations have the variable squared and take the form ax² + bx + c = 0, where a, b, c are constants and a ≠ 0. A quadratic function has a varied first derivative and therefore results in a curved graph known as a parabola with a point called vertex being the maximum or minimum point.
