Question

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)?

Answer 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 2

Answer:  B-To get from P to Q and from Q to R, you move down 3 units and 5 units to the right.
