Answer 7

@SamuelAlden917

It's not C.

@ilovenyc

It's A.

~~~~~~~

Let's look at graph C.

If we read the line on graph C,
we can see that when x = 0, y = -2

Let's plug that into then equation:

-4(0) + 3(-2) = 6

0 + (-6) = 6

-6 = 6

You see? The equation wouldn't be true, if we did that.

But just to double check, let's take ANOTHER ordered pair from graph C.

When x = 3, y = 2

-4(3) + 3(2) = 6

-12 + 6 = 6

-6 = 6

Again, the equation wouldn't be true.

So that means C isn't the answer.

Let's take a look at graph A, now.

One of the points on graph is when x = 0, y = 2

Let's plug that in.

-4(0) + 3(2) = 6

0 + 6 = 6

6 = 6

You see? It's true. It works out.

And just to double check, let's take another point from graph A.

When x = 3, y = 6

Let's plug it in:

-4(3) + 3(6) = 6

-12 + 18 = 6

6 =6

Again, it works out.

You've got your answer. And I hope I was able to explain all that so that you'd understand. Math is a little tricky to type out.

Answer 8

@InYourHead, thanks for explaining that to me of course your like 10 minutes late because i just turned this in, and found out like 5 minutes ago it was actually A, but thanks for explaining to me why its A.
