Find the area of

Given:

y = m₁x + c₁ … (1)

y = m₂x + c₂ … (2)

x = 0 … (3)

Explanation:

In triangle ABC, let equations (1), (2) and (3) represent the sides AB, BC and CA, respectively. Solving (1) and (2):

Thus, AB and BC intersect at B

Solving (1) and (3):

x = 0, y = c₁

Thus, AB and CA intersect at A 0,c₁.

Similarly, solving (2) and (3):

x = 0, y = c₂

Thus, BC and CA intersect at C 0,c₂.

∴ Area of triangle ABC =
