Area of the triangle formed by the points (-2, 1), (-3, 2) and (-4, 3) is :
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 0 sq.units
Three points given are: (-2, 1), (-3, 2) and (-4, 3)
Check whether they are collinear or not?
$⇒\frac{x_2-x_1}{y_2-y_1}=\frac{x_3-x_1}{y_3-y_1}$
$⇒\frac{-3+2}{2-1}=\frac{-4+2}{3-1}$
$⇒-1=\frac{-2}{2}=-1$
∴ The points are collinear and hence 0 sq.units.
