Question

(a) which two points should you use to find the equation of the model? explain.

Explanation:

Step1: Select representative points

Choose two points that lie on the line or are closest to it to best represent the linear - relationship. For a scatter - plot with a line of best fit, we want points that are not outliers and are well - positioned on the trend line. In this case, we can choose the points where the line of best fit intersects the grid lines clearly. For example, we can choose the point where $x = 0$ and $y\approx15$ (the y - intercept) and another point like $(5, 10)$ which also lies on the line of best fit. These points are representative of the overall linear relationship shown in the scatter - plot.

Answer:

We can choose the points $(0,15)$ and $(5,10)$ because they lie on the line of best fit and are representative of the linear relationship in the scatter - plot.
