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.
The graph must be a straight line, and it must pass through the origin.
because it is a methodical answer and that is why i am asking you
A linear relationship will show up on a graph as a straight line.
Linear = Straight line! So, a graph of a linear relationship is a straight line.
By definition, if you graph the relationship between two variables and the result is a straight line (of whatever slope) that is a linear relationship. If it is a curve, rather than a straight line, then it is not linear.
The graph is a straight line.
A linear graph shows a linear equation in which the value of one variable depends on the value of the other variable.
Yes. It can give insight as to whether there is a relationship between two variables, and if so, whether the relationship is direct or indirect; whether it is linear, polynomial, exponential, logarithmic; whether or not there are asysmptotic values; whether or not there is clustering; etc.
line graph or a scatter plot.
A straight line graph plotted on the Cartesian plane
A linear relation is a straight line. A non-linear relation is not - it mayor may not be be a curve.
It's a cartesian plane.
