Answer: 
Step-by-step explanation:
In algebra , We use algebraic expression to represent word phrase.
For example : 7 is added to p is written as "
"
-8 is multiplied by p is written as "
"
The statement : Suzy found the difference of x and 4 and then divided by 2.
First we express the difference of x and 4 as 
Then, we express entire statement : "difference of x and 4 and then divided by 2" =
Hence, the algebraic expression to represent this word phrase: 
9514 1404 393
Answer:
positive
Step-by-step explanation:
When considering the slope of a line, we usually choose "rise" and "run" so that "run" is positive, and "rise" measures the vertical change as one moves from left to right.
If we assume that "downhill" lines refers to lines that go from upper left to lower right (downhill to the right), then the rise is negative while the run is positive.

<em>Additional comment</em>
Here, we assume a line is considered to be "downhill" if it has negative slope. In the real world, "downhill" is the direction the ball rolls under the influence of gravity. That direction might be behind you, or to your left, instead of in front of you or to the right.
Definitions are important in math. "Downhill" is not a term that is widely used to describe lines, so we have to guess the intended meaning here.
A is the correct answer. slope is 6-3/0-1=3/-1=-3
so y-3 =-3(x-1)
