The answer I got was: 2: increasing
OpenStudy (anonymous):
do m=(y2-y1)/(x2-x1) to find your slope then plug in one of your known points into the point slope formula to find the equation of your line
OpenStudy (anonymous):
I took m=y2-y1= -2-1=-3 x2-x1= -1-(-4) = 3 Therefore, -3/3=2:increasing
OpenStudy (anonymous):
-3/3 is -1 and therefore should be decreasing
OpenStudy (anonymous):
Okay, I got it. Thanks a lot
