Answer:

Step-by-step explanation:
Given

Solving (a): Possible union elements
This is the represented by element with the largest number of the sets
i.e.

Solving (b): Possible intersection elements
This is the represented by element with the least number of the sets
i.e.

Answer:
y-2= - 1/11 (x-3)
Step-by-step explanation:
The slope is m=y2-y1/x2-x1=3-2/-8-3=1/-11=-1/11
Equation of a line is
y-y1=m(x-x1)
y-2= - 1/11 (x-3)
