i need an efs that shows the slope or angle of the linear regression line starting at 9:30 and ending at 4:00.

For instance if the linear regression line goes up from 9:30 on the angle of the line would be positive or up. If the linear regression line goes down starting at 9:30, the angle or slope would be negative or down.

Could someone help me with this efs?
