Show that the points (8, 1) (3,-4) and (2,-5) are collinear using determinant.
Answer : ### **The Principle** Three points, (x₁, y₁), (x₂, y₂), and (x₃, y₃), are **collinear** (lie on the same straight line) if and only if the area of the triangle they form is zero. ... points do not form a triangle and must lie on the same straight line. Therefore, the points **are collinear**....
