Question

Does adding 7+2 and then dividing by 2 help you find the midpoint of line segment JK? A. No because (7, 2) is not the coordinate of point J or K. B. Yes because (7+2) divided by 2 calculates the average, or midpoints, of the y-coordinates of points J and K. C. No because 7 should be added to 3, then multiplied by 2 to find the midpoint. D. Yes because (7+2) divided 2 calculates the average, or midpoint, of the x-coordinates of points J and K.

Answer 1

D.

The midpoint formula is ((x1 + x2)/2, (y1 + y2)/2). So (7 + 2)/2 gives the midpoint of the x-coordinates (if 7 and 2 are the x-values of J and K).
