Step-by-step explanation:
Let m : n be the required ratio. The point that divides the line segment joining the points (-3, -4) and (1, -2) is written as (0, t). Thus, the required ratio is 3 : 1

Answer:
Step-by-step explanation:
- Point A = (-3, - 4)
- Point B = (1, - 2)
- The line segment is divided by the y axis
- The ratio in which the line segment is divided
→ Let the line be divided in the ratio k : 1
→ Here it is given that the line segment is divided by the y axis.
→ Hence the coordinates of division = (0,y)
→ By section formula we know that,
where m₁ = k, m₂ = 1, x₁ = -3, x₂ = 1, y₁ = -4, y₂ = -2
→ Substituting the datas we get,
→ Equating it,
→ Cross multiplying it,
k - 3 = 0
k = 3
→ But we know that line segment is divided in the ratio k : 1
→ Hence the line segment is divided in the ratio 3 : 1
→ The section formula is given by,
