    To bisect a segment is to cut it in half. So, yes, Q is a point in the middle of segment PR. Since point Q cuts the segment PR in half, that means that segment QR has the same length as segment PQ. |----3y----|----3y---| |-----------|-----------| P........Q..........R |----------42---------| From the picture above, we get the equation: 3y + 3y = 42 6y = 42 y = 7
