Consider the following sets. u = {ordered pairs on a coordinate plane} a = {ordered pair solutions to y = x} b = {ordered pair solutions to y = 2x} which ordered pair satisfies a ∩ b?

(0,0)

Step-by-step explanation:

We have,

U = { (x,y) : x,y belong to real numbers }

A = { (x,y) : (x,y) is a solution of y=x }

B = { (x,y) : (x,y) is a solution of y=2x }

We need to find the ordered pair (x,y) that belong to AB.

Let, (x,y) belong to AB

i.e. (x,y) belong to A and (x,y) belong to B

i.e. y = x and y = 2x

i.e. x = 2x

i.e. x = 0

Now, substitute x= 0 in any of the equation say y = x, we get y = 0.

Hence, the ordered pair satisfying AB is (0,0).
