I forgot my math book and we have this graph puzzle thing and we have to explain why its linear and i dont remember what that means...please help me

Linear means the line is straight when graphed, and nonlinear means it has curves. The first nonlinear examples you will learn about are those that use exponents.

Algebraically, a linear function is a polynomial where the occurrances of x are to the power of 1. Examples of linear functions are:
f(x) = 6 - 2x
f(x) = (-1/5)x + 7
f(x) = 5(x + 2) + 3
The following are NOT linear functions:
f(x) = x^2 + 5x + 2
f(x) = x^3
f(x) = e^x + 2 {this is not a polynomial}
f(x) = sqrt(x)

Remember that all equations represent graphs so we call linear ecuations to those which graphic representation is a line it can have positive or negative slope or positive slope.

linear means straight when graphed, nonlinear is like an open polygraph. like a wierd doodle (lol

a linear function is a function that is a straight line
