Final answer:
The equation for the regression line is y = mx + b, where m represents the slope and b represents the y-intercept. The slope represents the change in the y-coordinate divided by the change in the x-coordinate, while the y-intercept is the point at which the line crosses the vertical axis.
Step-by-step explanation:
The equation for the regression line is y = mx + b, where m represents the slope and b represents the y-intercept. The slope m is the change in the y-coordinate divided by the change in the x-coordinate, while the y-intercept b is the point at which the line crosses the vertical axis.
