Consider expression 
First, you can factor it:
Since x is integer number, then you can see that x-1 is previous integer number (x-1 is 1 unit smaller than x).
Therefore, x-1 and x are two consecutive integers. When you have two consecutive integers, one of them is always even and one is always odd. Multiplying even integer number by odd integer number you always get even integer number.
Thus, 
is always even.
Slope = (2+5)/(-3-1) = 7/-4 = -7/4
answer is B -7/4
<h3>Answer: Choice C</h3>
Here's how the verification would look like
using the identity here
7 red, 8 yellow, 9 white......total = 24 roses
probability first pick is white : 9/24
probability second pick is yellow : 8/23
probability of both : 9/24 * 8/23 = 72/552 reduces 3/23 <====
Answer:
The slope of the line is the ratio of the rise to the run, or rise divided by the run.
