To determine if the expression \((7 + 2) ÷ 2\) helps find the midpoint of the line segment \(JK\), we need to understand what \(7\) and \(2\) represent.
If we assume \(7\) and \(2\) are the x-coordinates of points \(J\) and \(K\), then:
- \(7\) could be x-coordinate \(J_x\)
- \(2\) could be x-coordinate \(K_x\)
In that case, \((7 + 2) ÷ 2\) would indeed calculate the average of the x-coordinates, giving you the x-coordinate of the midpoint.
Conversely, if \(7\) and \(2\) represent the y-coordinates of points \(J\) and \(K\), the calculation would provide the midpoint of the y-coordinates.
Thus, the correct responses regarding this calculation are:
-
"Yes because (7+2)÷2 calculates the average, or midpoint, of the x-coordinates of points J and K." (if \(7\) and \(2\) are the x-coordinates)
-
"Yes because (7+2)÷2 calculates the average, or midpoint, of the y-coordinates of points J and K." (if \(7\) and \(2\) are the y-coordinates)
However, the context is needed to definitively claim whether they are x or y coordinates; if they are neither, then the last option would also apply: "No because (7,2) is not the coordinate of point J or K."
Without more context on what \(7\) and \(2\) represent, you cannot definitively choose a single answer.
