The slope of the line passing through the points (5 5) is 5/6. all of the following points could be on the line except? a. 2.5,2 b. 11,10 c. 8,7.5 d. -1,0 e. -7,-5 answer with explanation

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

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
