ANSWER
D) (a + 1, b + m)
EXPLANATION
The given line passes through (a,b) and has slope m.
The equation is:
When x=a+1, we obtain
This
Therefore,(a + 1, b + m) must also lie on this line.
The correct answer is D.
Answer:
Yes
Step-by-step explanation:
Given that a relation R is defined on the set Z by "a R b if a - b is divisible by 5
for a, b in the set of integers.
Reflexive:
We have
for any a,
i.e. (a,a) is related. Hence reflexive
ii) Symmetric:
If a-b is divisible by 5, then b-a is also divisible by 5. Hence symmetric
iii) Transitive
If
adding we get
Hence R is transitive
It follows that R is an equivalence relation on Z
