Question

Find the rati in which the y axis divides the line segment joining the points 4,-6 and -7,-4

Answer 1

Answer:

4:7

Step-by-step explanation:

Given points ;

A(4,-6)

B(-7,-4)

Given that y-axis divides the line AB.

Let it be in the ratio m:n

We know that on the x axis the x-coordinate = 0

Thu by using section formula ;

Thu by using section formula ;x = (mx2 + nx1)/(m+n)

0 = -7m + 4n/m+n

0 = -7m + 4n

7m = 4n

m/n = 4/7

Thus y-axis divides the line in the ratio m:n = 4:7
