# What is the difference between a linear function and a linear equation?

While all linear equations produce straight lines when graphed, not all linear equations produce linear functions. In order to be a linear function, a graph must be both linear (a straight line) and a function (matching each x-value to only one y-value).

Similarly one may ask, how do you know if its a linear equation?

There are actually multiple ways to check if an equation or graph is a linear function or not . First make sure that graph fits the equation y = mx + b . y = the point for y ; x = the point for x ; m = slope ; b = y intercept . By using this equation you'll be able to tell if it is a linear line or not .

What is an example of a linear equation?

Example: y = 2x + 1 is a linear equation: The graph of y = 2x+1 is a straight line. When x increases, y increases twice as fast, so we need 2x. When x is 0, y is already 1.
