Does adding 7+2 and then dividing by 2 help you find the find midpoint of line segment JK¯¯¯¯¯¯¯¯ ?

Question

Possible Answers:
Yes because (7+2)÷2 calculates the average, or midpoint, of the y-coordinates of points J and K. Yes because open paren 7 plus 2 close paren divided by 2 calculates the average, or midpoint, of the y -coordinates of points J and K. Yes because (7+2)÷2 calculates the average, or midpoint, of the x-coordinates of points J and K. Yes because open paren 7 plus 2 close paren divided by 2 calculates the average, or midpoint, of the x -coordinates of points J and K. No because (7,2) is not the coordinate of point J or K. No because open paren 7 comma 2 close paren is not the coordinate of point J or K. No because 7 should be added to 3, then multiplied by 2 to find the midpoint.

Answer 1

To determine if adding 7 and 2, then dividing by 2 helps find the midpoint of line segment JK, it's important to clarify what the coordinates of points J and K are.

If we assume that the numbers 7 and 2 represent the x-coordinates of points J and K, then:

1. Adding 7 + 2 gives the total of the x-coordinates of points J and K.
2. Dividing by 2 gives you the average of these two x-coordinates, which indeed calculates the midpoint in the x-direction.

Thus, the correct interpretation in this context would be:

Yes because (7+2)÷2 calculates the average, or midpoint, of the x-coordinates of points J and K.

If the numbers represent y-coordinates instead, then the interpretations would differ, as would the validity of the answer. Therefore, without specific coordinates for points J and K, the above statement is accurate under the assumption that 7 and 2 are x-coordinates.
