Final answer:
The line of best fit for the given points (0, 6)(2, 10)(-2, 2)(-1, 4) is y = 2x.
Step-by-step explanation:
The line of best fit for the given points (0, 6)(2, 10)(-2, 2)(-1, 4) can be determined by finding the equation of the line that minimizes the distance between the line and the points using the least-squares method.
To do this, we can use the slope-intercept form of a linear equation, y = mx + b, where m is the slope of the line and b is the y-intercept.
Using the least-squares method, the equation of the line of best fit is y = 2x + 6.
Therefore, the correct answer is a. y = 2x.
