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
To determine if a relationship is non-linear from a graph, look for patterns that do not form a straight line when plotting the data points. If the points curve or show a distinct pattern, such as a U-shape or an exponential increase, the relationship is likely non-linear. Additionally, analyzing the residuals from a linear regression can reveal non-linearity; if the residuals show a pattern rather than being randomly scattered, it indicates a non-linear relationship.
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.
To determine if a relationship is linear, you can express it in the form of a linear equation, typically written as (y = mx + b), where (m) represents the slope and (b) is the y-intercept. If the equation can be rearranged to fit this format, it indicates a linear relationship. Additionally, a linear relationship will show a constant rate of change, meaning the difference in (y) values for equal changes in (x) values remains consistent. If the graph of the equation produces a straight line, the relationship is confirmed as 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.
