1. Draw a straight line \( A B \) of any length. Mark a point \( F, 65 \mathrm{~mm} \) from \( A B \). Trace the paths of a point \( P \) moving in such a way, that the ratio of its distance from the point \( F \), to its distance from \( A B \) is (i) 1 ; (ii) \( 3: 2 \); (iii) \( 2: 3 \). Plot at least 8 points. Name each curve. Draw a normal and a tangent to each curve at a point on it, \( 50 \mathrm{~mm} \) from \( F \).

(a) Let $ P $ be a point not on the line $ L $ that passes through the points $ Q $ and $ R $. Show that the distance $ d $ from the point $ P $ to the line $ L $ is $$ d = \frac{\mid a \times b \mid}{\mid a \mid} $$ where $ a = \vec{QR} $ and $ b = \vec{QP} $ (b) Use the formula in part (a) to find the distance from the point $ P (1, 1, 1) $ to the line through $ Q (0, 6, 8) $ and $ R (-1, 4, 7) $

Let P be a point not on the line L that passes through the points Q and R. The distance d from the point P to the line L is d = |a x b| / |a| where a = QR and b = QP. Use the above formula to find the distance from the point to the given line: (5, 3, -1); x = 1 + t, y = 1 - 3t, z = 5 - 3t
