<h3>Slope Formula:</h3> is the y-coordinate of the second point
is the y-coordinate of the first point
is the x-coordinate of the second point
is the x-coordinate of the first point
Check the First example:
= 6
= -2
=3
= -9
6-(-2) is the same as 6+2; same with 3-(-9)
Simplify:
Is the slope negative? Nope!
<em>How about Option B?</em>
<em />
Right now it seems like the slope's negative, huh? Well, wait for it...
Kaboom!
Please remember that
A negative number multiplied/divided by a negative number equals... a positive! :-)
We have 2 options left: C & D.
We did it! The slope's actually negative :)
How about Option D (just to make sure the third option is right)
-9-(-8)/-1-2
-9+8/-3
-1/-3
Again we have a negative over a negative.
<h3>Therefore, the correct option is</h3>Hope everything is clear.
Let me know if you have any questions!
