To find the midpoint of line segment AB¯¯¯¯¯¯¯¯ , Fernando calculated 6.4+(−2.5)=3.9 . What should his next step be? (1 point) Responses Fernando has already made a mistake. He should have calculated 6.4+2.5=8.9 . Fernando has already made a mistake. He should have calculated 6.4 plus 2.5 equals 8.9 . Fernando has already made a mistake. He should have subtracted the x-values to get 8.9. Fernando has already made a mistake. He should have subtracted the x -values to get 8.9. Fernando should divide 3.9 by 2, then repeat both steps using the y-values. Fernando should divide 3.9 by 2, then repeat both steps using the y -values. Fernando should subtract the y-values.

Fernando has already made a mistake. He should have calculated 6.4 + 2.5 = 8.9.
To find the midpoint of a line segment defined by points A(x₁, y₁) and B(x₂, y₂), the correct formula involves averaging the x-coordinates and the y-coordinates separately. So after correcting his addition for the x-values, the next step would be to average them.
