Question

P is a point on the line segment joining the points (3, 2, –1) and (6, 2, –2). If x-coordinate of P is 5, then its y-coordinates is
(a) 2
(b) 1
(c) –1
(d) –2

Answer 1

Line joining (3, 2, –1) and (6, 2, –2) has same y-coordinate
∴ Any point on the line joining (3, 2, –1) and (6, 2, –2) will have same y-coordinate i.e 2

Hence, the correct answer is option A.
