Step-by-step explanation:
if Q - Find the ratio in which the y-axis divides the line segment joining the points (-4, -6) and (10, 12). Also, find the coordinates of the point of division
Answer
Let the y-axis divide the line segment joining the points ( -4, -6 ) and ( 10, 12 )in the ratio k:1 and the point of the intersection be ( 0, y ).
Using section formula, we have
10k+ ( -4)k + 1 . 12k + (-6 )k + 1 = 0, y∴ 10k - 4k + 1 = 0 ⇒ 10k -4 = 0 ⇒ k = 410 =25Thus the y-axis divides the line segment joining the given points in the ratio 2:5∴ y = 12k + (-6)k + 1 = 12 x 25 -625 + 1 =24-3052+55 = -67Thus, the coordinates of the point of division are 0, -67
