Answer:
The slope is -2.
Step-by-step explanation:
The slope formula is (y1-y2)/(x1-x2)
or change in y / change in x.
First, you plug in your numbers. I will use (2, 7) as (x1, y1)
(1-7)/(5-2)
Next, simplify.
(-6)/(3)
or
-2
And that's your slope!
Trust me: You must know how to do this basic factoring yourself.
x^2 -5x - 6 factors into (x-6)(x+1). Note how I got that: -6 is the product of 1 and -6, and -6 + 1 = -5.
You could also factor this by grouping:
x^2 -5x - 6 = x(x-6) + 1(x-6). Note how the middle terms combine to produce -5x and how (x-6) is a factor common to both terms; this leaves (x+1). So the factors are (x-6)(x+1).
