Answer:
y = 0.75x + 45
Step-by-step explanation:
The line of best fit is a line that describes in a better way the distribution of the points. Therefore, the best fit will be like
Then, the equation of this line can calculate using two points in the line, for example (x1, y1) = (2, 6) and (x2, y2) = (6, 9). So, the slope of the line is
Finally, the equation of the line is
Therefore, the answer is
y = 0.75x + 45
