Answer:

Yes they can all be written in y = mx + b. You just have to move the terms around.

Step-by-step explanation:

y = 2x -3, this is already in slope-intercept form

Now, y - 2 = x + 2: We can add 2 on both sides to cancel out the one on the left side:

y - 2 = x + 2

y - 2 + 2 = x + + 2

y = x + 4 <-- This is in y = mx + b form

Now the last one, 3x = 9 + 3y

We can first divide all terms by 3,

3x = 9 + 3y

/3     /3   /3

x = 3 + y: Then we can subtract 3 from both sides:

x - 3 = 3 + y - 3

x - 3 = y

These are all linear equations because none of the x's have bigger powers than 1. x^2 is a quadratic equation and x^3 is cubic equation.

Order the following numbers from least to greatest :

You can choose to put all the numbers into decimals or fractions.
In this case, I will put the numbers all in decimals. 
We already have 2.07, -2.67, and 2.67 
2 \frac{7}{10} in a decimal is 2.7 because 7 is in the 'tenths' place and ten was our denominator
So all of our numbers are 2.7 2.01 2.67 and -2.67
Obviously a negative number will be last and you can line the other numbers to see which is the greatest
2.67
2.70 (if there is nothing there we can always put a zero)
2.01
So the first digit is all 2 so we look at the next digits which are 6, 7, and 0 
You should know how to order those numbers, so do the same here.
-2.67, 2.01, 2.67 2\frac{7}{10} (we had to change it back to a fraction) 
Hope that helped :)
