The data is equally spaced in x so let's start by taking first differences.
4-9 = -5
-1-4 = -5
-6 - -1 = -5
-11 - -6 = -5
Hmmm. I detect a pattern. That tells us we have a line and the slope is -5.
We read off the y intercept from x=0 as -1.
So our equation in slope intercept form is
y = -5 x - 1
or as a function

Your answer for this is C
Answer:
D
Step-by-step explanation:
Remember, area equals width x height so you can set up this equation.

Solving for w,

Simplifying,

Thus, D is the answer
Answer:

Step-by-step explanation:
8x + 4y = 2
-8x - 8x
____________
4y = -8x + 2
__ _______
4 4
y = -2x + ½

The answer is x=-5.5 . 2x-3 = 4x+8 . subtract 2x from both sides and then subtract 8 from both sides and get -11=2x . then divide both sides by 2 to get . -5.5=x
