How can you tell if something is a linear function?

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 .

Just so, what is the formula for a linear function?

The formula y = mx + b is said to be a linear function. That means the graph of this function will be a straight line on the (x, y) plane. Since we will be graphing (x, y) points, though, we will do our thinking with the 'y = mx + b' form for a while.
