Answer:
Collinear
Step-by-step explanation:
Slope of the line made by any point must be same in all cases.
Slope of line through (2, -3) and (5, 5):
= (5 - (-3)) / (5 - 2)
= 8/3
Slope of line through (5, 5) and (1/2 , -7):
= (-7 -5)/(1/2 - 5)
= - 12/( (1 - 10)/2 )
= - 24/(-9)
= 8/3
As the slope is same in each case, these points are collinear.
