Question

Findthe ratio in which y-axis divides the line segment joining the points A(4, -7), and B(-2, -3)

Answer 1

Answer:

Let the ratio in which y- axis divides the line be a:1

Coordinate of point is (y, 0)

x = mx₂ + nx₁/ m + n

0 = a(-2) + 1(4)/ a + 1

0 = -2a + 4/a + 1

0 = -2a + 4

2a = 4

a = 2

The point divides the line in ratio a:1 = 2:1
