Question

find the ratio in which the line segment joining the point 5,-6and -1,-4 I'd divided by y axis​

Answer 1

Answer:

5:1

Step-by-step explanation:

Let the ratio be $k:1$

Since it is cut by y axis, the x- coordinate of the y axis is 0.

Let the point on the y axis be $(0,y)$

By section formula,

$x = \frac{mx2+nx1}{m+n}$ when a line segment joining the point (x1,y1) and (x2,y2) is divided by (x,y) in the ratio of m:n

P(5,-6)

Q(-1,-4)

$0=\frac{k(-1)+1(5)}{k+1}\\0=5-k\\k=5$

The ratio of division is 5:1

Answer 2

Answer:

using section formula

=m1×x2+m2×x1/m1+m2 or m1×y2+m2×m1/m1+m2

then you get your answer?
