Question

Collinear points by trigonometry value are A (1,-3) , B (2,-5) , C (-5 , -7 )

Answer 1

Answer:

points are not co linear

Step-by-step explanation:

Collinear points by trigonometry value are A (1,-3) , B (2,-5) , C (-5 , -7 )

Points will be co linear if equation of line is same.

Line AB

y = mx + x

m =(y2 - y1)/(x2-x1)

m = (-5 -(-3) )/(2-1)

=> m = -2/1

=> m = -2

y = -2x + c

point A for x = 1 ,y =-3

-3 = -2(1) +c

=> c = -1

y = -2x-1

If C point is co linear then point C will hold true for the equation

-7 = -2(-5) -1

=> -7 = 9

which is not true

so points are not co linear
