CO-ORDINATE GEOMETRY OF STRAIGHT LINE (II)

ASSESSMENT: Determine the solution of the following:

1. Find the distance between the following pairs of points: (i) x(3,-9) and y(-4,15)  (ii)  p(-2,-7)and q(8,-9).
2. Find the gradient and intercept of the following: (i) 6y-8x+3 = 0  (ii) x + 6y – 10 = 0 (iii) 3x = 15 – 5y
3. Find the mid-points of the line joining the points: (i) (-6,-12) and (4,3)  (ii) (p,q) and (q,p) (iii) (0,11) and (12,-9).
