Question

solve the question number 14​

Answer 1

Answer:

Step-by-step explanation:

it is easy....... use the formoula 1/2(x1(y2-y3)+x2(y3-y1)+x3(y1-y2)

according to this formula if triangle will not form then the points are not colinear

Answer 2

⭐Hola User____________________

⭐Here is Your Answer...!!!

____________________________

↪Actually welcome to the concept of the AREA OF A TRIANGLE...

↪BAsically we know that, when in a cartesian plane , the area of a triangle is equal to ZERO , then we can definitely say THAt the given points are collinear in nature ..

↪Thus when the area of triangle of any three points = 0 m then we can the points are collinear

↪BUT

↪when the area of the triangle is not equals to ZERO ,then the pointd are said to be non collinear ..

↪the area of triangle is given by formula. .

⭐Area = 1/2 ( x1 ( y2 - y3 ) + x2 ( y3-y1) + x3 ( y1 - y2) )

↪if applying this formula for above given coordinates gives a NON - ZERO answer , then we can say that the points are NON COLLINEAR
