The coefficient of x is the value for slope in y-intercept form, and the number that we add or subtract is our y-intercept. So in this case, we want to look for a "-2" in front of x and a +4 in the equation.
Answer choice A fulfills those conditions. (I am also assuming that answer choice A should have had an x in it, but you accidentally forgot to type it.)

Answer:
w=p/2-l
Step-by-step explanation:
you have to simplify the equation p=2(l+w).
1) Isolate the variables l and q
p/2=l+w
2) Subtract the length from the width.
p/2-l=w
3) The answer is b, or w=p/2-l
Answer:
Positive
Step-by-step explanation:
There are a couple ways we can go about this.
First, we can see that as x increases, so does y, so that means its positive
For perspective, if x is the amount of time and y is the number of sales, we can see that the sales are going up and not going down or staying at the same place
If you wanna check your work on that, you can plot two points and find the slope using y1-y1/x1-x2 and the slope will be positive.
We can also use the process of elimination, we know it can't be zero because it's not a straight, horizontal line and we know its not undefined because it isn't a straight vertical line, so it's between negative and positive, and since the line is going up, that means that it's positive.
Answer:
C)
Step-by-step explanation:
- π can be added to π to get a rational number
π + (-π) = 0
0 is a rational number
