Answer:
The equation of the line passing through the given points.
(1,-5) and (-4,5) is
Step-by-step explanation:
Given:
Let,
point A( x₁ , y₁) ≡ ( 1 ,-5)
point B( x₂ , y₂ )≡ (-4 , 5)
To Find:
Equation of Line AB =?
Solution:
Equation of a line passing through a points A( x₁ , y₁) and point B( x₂ , y₂ ) is given by the formula Two -Point Form,
Now on substituting the slope and point A( x₁ , y₁) ≡ ( 1 ,-5) and B( x₂ , y₂ )≡ (-4 , 5) we get
The equation of the line passing through the given points.
(1,-5) and (-4,5) is
