How do you know a graph is linear?

You can tell if a table is linear by looking at how X and Y change. If, as X increases by 1, Y increases by a constant rate, then a table is linear.

An equation is considered linear, if it is in the form of. y = mx + b. where m is the slope of the equation, and b is the y-intercept.

First of all the shape of the graph is a straight line. Every linear graph is nothing more than a straight line so if there is any curves in it, it's not linear. The other way to tell is look at its equation.
