question
graph the line of best fit.
click to plot a point. two points plot a line.
click a plotted point to delete it.
Step1: Analyze the scatter plot's trend
Observe the general direction of the data points. They seem to have a positive correlation (as x increases, y generally increases).
Step2: Identify two representative points
Find two points that are close to the center of the data cluster. For example, pick a point from the lower - left cluster and a point from the upper - right cluster that seem to lie along the trend.
Step3: Draw the line
Connect the two chosen points with a straight line. This line should pass through the middle of the data points, balancing the number of points above and below the line as much as possible.

To draw the line of best fit, follow these steps:
- Identify the general trend of the scatter plot (positive in this case, as y - values tend to increase with x - values).
- Select two points that lie close to the center of the data distribution. For example, if we consider the lower - left and upper - right regions of the data cluster, pick a point like (x₁,y₁) from the lower - left and (x₂,y₂) from the upper - right where the points are representative of the overall trend.
- Use a straight - edge (or the plotting tool) to draw a line connecting these two points. The line should be positioned such that it approximately balances the number of data points above and below it.
(Note: Since this is a drawing task, the final answer is the visual line of best fit drawn through the scatter plot points following the above steps.)
