The table shows the heights in inches of trees after they have been planted. Determine the equation which relates x and y.
fenix001 [56]
To get the that relates x and y, we choose two points on the table and use the equation of a straight line as follows:

Recall that the equation of a staight line is obtained from the formula
\frac{y-y_1}{x-x_1} = \frac{y_2-y_1}{x_2-x_1}

Using the points (30, 18) and (36, 24), we have
\frac{y-18}{x-30} = \frac{24-18}{36-30}= \frac{6}{6} =1 \\  \\ \Rightarrow y-18=x-30 \\  \\ \Rightarrow y=x-30+18 \\  \\ \Rightarrow y=x-12
