Value of x for which the two points are on the line with the given slope (1,-1) and (x,7): undefined is 
.
<u>Step-by-step explanation:</u>
Here we have to Find x so that the two points are on the line with the given slope (1,-1) and (x,7): undefined . Let's find out:
We know that for any two points given as 
slope of line is determined by :
⇒ 
According to question we have two points as 
∴
⇒
⇒ 
But slope is undefined which is only possible when denominator is zero i.e.
⇒ 
⇒
Therefore , Value of x for which the two points are on the line with the given slope (1,-1) and (x,7): undefined is .
Answer:
Independent.
Step-by-step explanation:
Independent events:
Two events, A and B, are said to be independent if the probability of both happening is the same as the multiplication of the probabilities of each happening, that is:
Thus, P(A and B)=P(A)•P(B) is used when two events are independent.
