Question

In what ratio Does Y-axis divide the line joining (5,5) and (-2,-2) ??

can anyone solve it fast plzzits from coordinate. geometry ​

Answer 1

Answer:

5:2 I think it would be the answers of these

Answer 2

Answer:

Y- axis divides the line in the ratio 4:3

Step-by-step explanation:

Coordinates: A (5,5) & B (-2,-2)

Let the ratio be m1:m2;

If the line is divided by y-axis, then the 'x' coordinate should be zero. So,

SECTION FORMULA:

P(x,y) = [m1x2 + m2x1/m1 + m2 ,  m1y2 + m2y1/m1 + m2]

P(0,y) = [-2m1 + 5m2/m1+m2 , -2m1 + 5m2/m1+m2]

Therefore,

0 = -2m1 + 5m2/ m1+m2

⇒ m1 + m2 = -2m1 + 5m2

⇒ 3m1 = 4m2

Therefore,

m1 : m2 = 4 : 3
