find the equation of the line which passes through the points (–1, 1) and (2, – 4).
Answer :
Given points (-1, 1) and (2, -4)
We know that the equation of the line passing through the points (x1, y1) and (x2, y2) is given by
⇒ 3 (y – 1) = (-5) (x + 1)
⇒ 3y – 3 = -5x – 5
⇒ 3y – 3 + 5x + 5 = 0
⇒ 5x + 3y + 2 = 0
Ans. The equation of the line is 5x + 3y + 2 = 0.
