Answer:
The ratio of division is 5:1
Step-by-step explanation:
As the dividing point lies on y-axis
so the coordinates of that point is (0,y)
Let, the ration at which that point divides be m1 and m2
According to section formula;
x coordinate of that point = ( m1x2+m2x1) /(m1+m2)
we know that, x coordinate = 0,x2= (-1) and x1=(5)
so, 0 = [m1(-1)+m2(5)]/(m1+m2)
→ 5m2-m1 = 0(m1+m2)
→ 5m2 - m1 = 0
→ 5m2 = m1
Ratio of division = m1:m2
= 5m2 : m2 [ since m1 = 5m2]
= 5:1
