It will be a straight line.

In any words, a linear graph is a graph in the form of a straight line which extends unbroken in opposite directions. It can be modeled by the equation y=mx+b in which y (or f(x) as it's commonly called) is the line, m is the slope (rise/run) of the line, x is a value which you substitute into the equation for an output of y (that's how you fine the points of a line, an input of x and an output of y for the point (x,y)), and b is your y-intercept (the value of y if x=o, also where the line crosses the y-axis. Every line will have a y-intercept unless it's undefined (ex: x=6 produces a straight vertical line which crosses the x-axis as 6. every point for the line x=6 has 6 as an x value so they look like (6,y).))

How can you tell if a graph is an example of linear growth?

Linear growth means that the graph is a straight line.


How can you tell if a graph is a linear function?

The word linear means in a straight line. If the graph is a line, it is linear. Also, linear equations are of the first order; they contain a variable but not a square (or higher power) of a variable. If the equation contains x2 it is not linear.
