Given are five observations for two variables, x and y.

$\begin{matrix} x_i & \text{1} & \text{2} & \text{3} & \text{4} & \text{5}\\ \hline y_i & \text{3} & \text{7} & \text{5} & \text{11} & \text{14}\\ \end{matrix}$

Try to approximate the relationship between x and y by drawing a straight line through the data.

Solutions

VerifiedThe goal of this task is to draw a line in the scatter plot which will be a good approximation of the relationship between variables $x$ and $y$.

*Picture 2* below shows a straight line that visually fits the data points.

In this exercise, we sketch a straight line on the scatter diagram, where the line approximates the relationship between the variables.

*Which straight line best approximates the relationship between the variables?*
