We can already tell the slope must be negative, because as the \(x\) value increases the \(y\) value goes down.

We eliminate B and C to get choices of A and D.

A has a y-intercept of a positive number while D has a y-intercept of a negative number. From the points we can see that at \(x=-1\), \(y=5\) and at \(x=2\), \(y=-1\). We can see that at \(x=0\) the answer will be positive, so A is the correct answer.

We can check by graphing.

The red line is \(y=-2x+2\) and we can see that seems like the best line.

You are very welcome!

Thanks, that helped!

Let's see all of them.

It seems like for all of them B overpowers, except for C.

A, B, D have mostly B's but C has a general mix, therefore, the answer is C.

You are very welcome!

This is an expression, so we can only simplify it as much as possible!

Do we see like terms? Yes, we see the \(x\) three times and they are all to the same degree, \(x^1\).

Therefore, we can add the coefficients of them and get \(2x-5y+5x+3x=2x+5x+3x-5y=10x-5y\) .

The expression is \(10x-5y\).

To simplify even more, if you want, we can factor out a 5.

\(10x-5y=5(2x-y)\)

You are very welcome!

:P

You can graph it, just like this.

Or, you can do it with math.

The x-coordinate means that the y value must be zero. We can plug in \(y=0\) and get \(3x=7\) .

Simplifying we get \(x=7/3\) , so the x-coordinate is 7/3.

You are very welcome!

Well, this is tedious but simple.

After counting all the characters we find that there are a total of 100 characters (at least when I counted). From this all we do is see that the number of "e"s to the number of total characters is \(18/100\), or \(9/50\).

You are very welcome!
