Answer: .
Step-by-step explanation:
As we know ,
The slope of a line that passes through and
is given by :
The slope of a line that passes through (1 , 7K), and (-3,5K) =
Hence, the slope of the given line is .

Answer:
A
Step-by-step explanation:
according to tangent property
we get
- AM=BM
- AN=CN
- BK=CK
Given that
- AM=6
- BK=4
Thus our equation is
substitute the given values
simplify multiplication:
simplify addition:
cancel 20 from both sides:
divide both sides by 2:
AN=CN
hence,CN=7
therefore our answer is A
