In this case, the model that represents y as a function of x has the form of a linear equation: y=mx, we can find the value of m by following this formula:
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
To find the value of m, we just need to replace some pairs of x-y values from the table, for example, we can choose the points (3,196.5) and (13,851.5)
[tex]m=\frac{851.5-196.5}{13-3}=\frac{655}{10}=65.5[/tex]
Then the equation is:
[tex]y=65.5x[/tex]
