is the slope between these two points. To figure out the slope between two points, we need to find the rise over run, which is the change in the <em>y value over the change in the x value</em>. This becomes:

And simplifies to:

, meaning that the slope between these two points is

.
<span>The answer is She should have multiplied by 2 instead of dividing by 2.

No 3/4 is NOT equal to 5/6
Malaria proved that the equation you need to add the parenthesis first
X-3y=-5
-(x+3y=1)
-------------
-6y=-6
y=1
x=-2
