Question

8. Find the equations of the line joining the points
(a) A (1, 1) and B (2,3)
(b) P (3, 3) and Q (7.6);
(c) L(a, b) and M(b, a).

Step by step solution ? ​

Answer 1

Step-by-step explanation:

i) for equation use

(y-y1) = (y2-y1)/(x2-x1) x (x-x1)

(y-1) = (2)/(1) x (x-1)

y-1 = 2x - 2

2x - y -1 = 0

similarly

ii) (y-3) = 3/4 x (x-3)

4y -12 = 3x - 9

4y -3x -3 = 0

hope it helps you
