Answer:
<h2>B. -10</h2>Step-by-step explanation:
Answer: C) linear, straight, and decreasing
------
If you graph the table, you get something that looks like image 1 attached. Connect the points to get the graph (see image 2). You can see the graph is decreasing, meaning that it goes down (y decreases) as x increases. That means answer choice A is wrong.
You're left with choices B, C, and D. Note that linear means that the graph must be a straight line, so you can rule out choice B.
Finally, see if the graph is linear. It looks straight, and if you try to find an equation, you get y = -2x + 14, which is an equation of a linear line in slope intercept form! (y = mx + b) That means answer choice C is correct!
