Answer :
Given:
x + y − 4 = 0, 2x − y + 3 = 0 and x − 3y + 2 = 0
To find:
Point of intersection of pair of lines.
Concept Used:
Point of intersection of two lines.
Explanation:
x + y − 4 = 0 … (1)
2x − y + 3 = 0 … (2)
x − 3y + 2 = 0 … (3)
Solving (1) and (2) using cross - multiplication method:
⇒ x = 1/3, y = 11/3
Solving (1) and (3) using cross - multiplication method:
⇒ x = 5/2, y = 3/2
Similarly, solving (2) and (3) using cross - multiplication method:
⇒ x = - 7/5, y = 1/5
Hence, the coordinates of the vertices of the triangle are
