Given : Line 1 ( 2, 5 ) , (-3 , - 5)
Line 2 ( 3, 0) , ( 0 , - 3)
To Find : Point of intersection
Solution:
Line 1 ( 2, 5 ) , (-3 , - 5)
y - y₁ = { (y₂ - y₁)/(x₂ - x₁) } (x - x₁) where m = (y₂ - y₁)/(x₂ - x₁)
y - 5 = {( -5 - 5)/(-3 - 2) }(x - 2)
=> y - 5 = 2 (x - 2)
=> y - 5 = 2x - 4
=> 2x - y = - 1
Line 2 ( 3, 0) , ( 0 , - 3)
y - 0 = {(-3 - 0)/(0 - 3)} ( x - 3)
=> y = x - 3
=> x - y = 3
2x - y = - 1
x - y = 3
=> x = - 4
y = -7
point of intersection ( - 4 , - 7)
