Question

In what ratio does the y- axis divides the line segment joining the points P ( - 4, 5) and Q( 3,-7) ? Also find the coordinates of point of intersection.

Answer 1

If two points p(x1,y1) and q (x2,y2) , then y axis divides the line segment in ratio (-x1/x2)

So, ration in which y axis will divide the line segment joining the point p (-4,5) and q (3,-7)

= - (-4)/3 = 4/3

Answer 2

Answer:

Step-by-step explanation:

$A(0,y)= [(kx_{2} +x_{1}) / k+1, (ky_{2}+y_{1})/k+1]\\=[3k-4/k+1, -7k+5/k+1)\\\\0=3k-4/k+1\\3k-4=0\\3k=4\\k= 4/3\\\\k:1=4/3\\Ratio= 4:3$

$Coordinates: (0,y)\\y= -13/7$

Substitute k=4/3
