Question

What is the answer for 4x + 2y = 12

Answer 1

y=-2x+6

Explanation:

You want to to turn the given equation 4x+2y=12 into y=mx+b

** m is the slope and b is the y-intercept

The first step is to isolate y. First subtract 4x from both sides:

4x+2y=12

2y=-4x+12

Now you have y mostly isolated, all you have to do is divide both sides by 2:

2y=-4x+12

y=-4/2x +12/2

y=-2x +6

Now you have your equation, plug in values for x to find y to fill in the table:

ex: y=-2(2)+6

y= -4+6

y= 2

** an order pair ex.: (2,2)

Answer 2

(1,4), (2,2) (3,0)

Explanation:

adjust the equation so that the y is isolated so subtract 4 x

2y=4x +12

Every number is divisible by 2 so you can further isolate the y

y=-2x+6

Plug your x coordinates into the equation so get the y coordinates
