Answer:
The correct option is d
Step-by-step explanation:
From the question we are told that
The set of people in a certain community who were asked if they subscribe to an information source is U
The set that subscribes to The Daily Informer is D
The set that subscribe to News Magazine is N
Here the universal set is U
Now the word at least here means that the person can subscribe to one or two of the information source , but the person cannot subscribe none of the information source
Now to get the set that represents the set of people surveyed who subscribe to at least one of the two news sources , we need to carry out a union operation on the sets representing the two news source , this can be mathematically represented as
So the sets that will contain all the people in the community that subscribe to at least one of the news source is L

Answer:
The equation of the line AB is y - x -4 = 0
Step-by-step explanation:
The points are A (10,14) and B(2,6)
Now, slope of the line AB :
or, =
So, slope of the equation AB = 1
Now, by SLOPE INTERCEPT FORM:
The equation of line is given as : y - y0 = m (x-x0)
So,the equation of line AB is y - 6 = 1(x-2)
or, y - 6 -x + 2 = 0
or, y - x -4 = 0
Hence, the equation of the line AB is y - x -4 = 0
