Which best explains how you know that P(2, 7)P(2, 7) is on the same line as Q(7, 4)Q(7, 4) and R(12, 1)R(12, 1)?
Find the equation of segment QR by 'Two point form'. Ping me if you don't know what it is. If coordinates of point P satisfies this equation, then it implies that point P lies on the same line as Q and R does ;-)
Answer: B-To get from P to Q and from Q to R, you move down 3 units and 5 units to the right.
