Question

Which graph represents 2x+2y=4

Answer 1

Hi!

We need to isolate y on one side.

Subtract 2x from both sides.

2x - 2x + 2y = -2x + 4

2y = -2x + 4

Divide by 2 on both sides.

2y/2 = -2x/2 + 4/2

y = -x + 2

The slope is -1/1.

The y intercept is 2.

So the answer is D. (the last one)

Hope this helps! :)

Answer 2

Hey there!

Your answer: Graph D

We would want to find the graph that would stay positive, and not negative. As we look at Graph D, it moves 2 from the right, and also 2 up. Which indicated both 2x+2y=4

Answer: Graph D
