I need a help in this question

Explain the difference between linear and quadratic equation?:confused:

A linear equation has as highest power of x, 1. A quadratic equation has an x of power 2.

Is there any more diffrence?

A linear equation is a straight line, whereas a quadratic equation is a curve.

A linear equation has a fixed gradient but a quadratic equation has a gradient which keeps on changing.

A linear equation has no turning (or stationary or maximum or minimum) but a quadratic equation has.

EDIT: Of course, all these are true provided the equations are on the same axis, and they are no modulus functions.

This very much depends on the axes of the graph o_O
If one axis is x^2 and one is just x, then a quadratic graph will be straight... Sorry to be penickity!
