Question

verify whether the following points are collinear or not , A(1, -3) , B(2, -5) , C(-4, 7)​

Answer 1

Answer:

yes it is colliner

Step-by-step explanation:

as these points lies in same quadrants

quadrant 2 and quadrant 3

Answer 2

Area of triangle = 1/2[1(-5-7)+2(7+3)-4(-3+5)]

= 1/2[1(-12)+2(21)-4(2)]

= 1/2[-12+42-8]

= 1/2[-20+42]

= 1/2[22] = 11 sq. units

But we know that,

If three points are collinear so, area of∆ is 0

so, these points are not collinear.
