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
