Any shape other than a straight line!
Linear graphs make straight lines. Non-linear graphs make thins like parabolas, hyperbolas, and ellipses
A linear relation is a straight line. A non-linear relation is not - it mayor may not be be a curve.
Linear describes a relationship that exhibits a straight line when plotted on a graph, for example. Non liner is any thing other than a straight line.
A graph is non-linear if it does not form a straight line when plotted on a Cartesian coordinate system. This can be identified by observing curves, bends, or changes in direction as you move along the graph. Additionally, if the relationship between the variables does not follow a constant rate of change (i.e., the slope varies), it is indicative of a non-linear relationship. Common examples include quadratic, exponential, and logarithmic functions.
The graph of a linear function is a line with a constant slope. The graph of an exponential function is a curve with a non-constant slope. The slope of a given curve at a specified point is the derivative evaluated at that point.

You can decide from a graph wheter a ralationship is linear or non linear if the line is staight is linear but if the line is not straight is not linear.
a non linear graph pretty much means the points on the graph do not create a straight line. in order for a graph to be linear both the x axis and y axis have to increase/decrease at a constant rate, while in a non-linear graph when you connect the point it creates a line that isn't straight. however, in experimental data if the points are a bit off, but still in one general area, it can be considered linear.
no you cannot
linear: LINE example--- line non-linear: not a LINE example--- parabola The other possibility is a graph with a non-linear scale. First a linear scale will have each unit represent the same amount, regardless of where you are on the scale. A semilog scale, has a linear scale in the horizontal direction, and a logarithmic scale in the vertical direction. Exponential functions (such as ex & 10x), will graph as a straight line on this type of graph scale). A logarithmic or log-log scale, has logarithmic scales on both horizontal and vertical axis. Power functions (such as sqrt(x), x2 and x3), graph as a straight line on these scales. See Related Link

A non-linear graph.
Equations without exponents generate straight lines when graphed, hence are called linear. If there is an exponent such as x2, then you get curved lines, and the graph is non linear.
