Question

find the ratio in which y axis divides the line segment joining the points (6,-4) and (2,-4). also find the point of intersection​

Answer 1

Answer:

Let the ratio is a:1 & on y axis, x = 0

so,

$\frac{a \times 2 + 1 \times 6}{a + 1} = 0$

$2a + 6 = 0$

$a = - 3$

so y axis divide line segment externally in 3:1.

Now y coordinate of point is

$\frac{ - 3 \times 4 + 1 \times 4}{3 - 1} = - 4$

so point of intersection is ( 0 , -4 ).

Answer 2

Answer:

the answer is in the attachment

Step-by-step explanation:

since point lies on y axis so x coordinate will be 0 ..HOPE IT HELPS
