The relationship is said to be linear if one variable
Now check whether the relationship is linear or not.
As
Now find the equation.
Take
Equation is given by
In words, the relationship can be defined as follows:
Total bill is
Now draw the graph.
First find points that can be used to plot the graph.
x | y |
