What is the given ordered pairs of 6x+2y=12 the Right answer

Question

Ordered pairs of 6x+2y=12

Answer 1

You only gave us part of the problem, but here's the general approach.  First, put the equation into the slope-intercept form (y = mx + b):

 

6x + 2y = 12

2y = -6x + 12

y = -3x + 6

 

To find ordered pairs, simply plug in any value for x and compute the corresponding y.  For example, let's try x = 3:

 

y = -3x + 6

y = -3(3) + 6

y = -9 + 6

y = -3

 

So the ordered pair is (x,y) = (3,-3)

 

If they give you a list of ordered pairs, plug the x value into the equation and see if you get the same y value in the ordered pair.  If you do, then that ordered pair is on the line; otherwise it is not.
