to find the midpoint of line segment AB, Fernando calculated 6.4 +(-2.5)=3.9. What should his next step be?

Question

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 calculated 6.4+2.5=8.9
Fernando should subtract the y-values
Fernando Should divide 3.9 by 2, then repeat both steps using the y-values

Answer 1

To find the midpoint of line segment AB, Fernando should first calculate the average of the x-coordinates (which seems to be where he made an error) and then do the same with the y-coordinates. Since he incorrectly added the x-coordinates instead of using the midpoint formula, his next steps should be:

Fernando should divide each of the sums he finds (after correctly calculating the totals for the x-values and y-values) by 2 to find the midpoint.

Since he made an error in his initial calculation, the correct interpretation would be:

Fernando should subtract the y-values.

This means he needs to find the correct x and y sums, then divide by 2 to find the midpoint properly.
