So slope formula
Y2-y1/x2-x1
To lay on the line, the filled in slope formula with point one (5,5) and another point (A,B,C,D,E) should be 5/6
So lets find the answer :)
A (5-2)/(5-(5/2))= 3/(-5/2) = 6/-5
B (10-5)/(11-5)= 5/6
C (7,5-5)/(8-5)= (2,5/3)= (5/2)/3= 5/6
D (5-0)/(5-(-1))=5/6
E (5-(-5))/(5-(-7))= (10/12)= 5/6
So the first one doest lay on the line
Hope this helps
