Answer:
m1 : m2 = 1:3
Step-by-step explanation:
The line segment is divided by the Y-axis.
therefore the point is (0,y)
Given, A (3, 8) and B(-9, 3)
A(x1,y1) B( x2,y2)
y = 0
= (m1x2+m2x1)/m1+m2 = 0 (cross multiply)
= m1x2+m2x1 =0
= -9m1 + 3m2 = 0
= -9m1 = -3m2
= m1/m2 = -3/(-9)
= m1:/m2 = 1/3
= m1 : m2 = 1:3
