Question

Name 3 ordered pairs which belong to the relation 2x+3y=6
~~How do you do this question?

Answer 1

Set a value for y and solve for x. That's one ordered pair.
Repeat for other values of y to get two other pairs.
Example: y=0, x=6/2=3, so (3,0) is an ordered pair belonging to the relation.

Answer 2

so you just pick random numbers for x and y and solve them?

Answer 3

Yes, since the domain of the relations is any real number.

Answer 4

if you pick 0 for x would it be 2(0)+3y=6 and then pick another number for y?

Answer 5

Yes, you can pick a number for x as well.

Answer 6

if you pick 0 for x, you plug it in to get


2(0)+3y=6


0+3y = 6


3y = 6



Now solve for y to get



3y = 6


3y/3 = 6/3


y = 2


So when x = 0, y = 2


So we have one ordered pair (0, 2)

Answer 7

If you pick x=0, then you solve for y=6/2=2,so (0,2) is another pair.
