Answer:
0
Step-by-step explanation:
Slope = (y2-y1)/(x2-x1)
= (-5--5)/ (9--8)
= (-5+5)/(9+8)
= 0/17
=0
The slope it 0
This is a horizontal line because the y value doesn't change. If the y value doesn't change, the slope it zero.
Two sides would=2 which would have 2 sides had up to 4, and the other two sides would= 1 which would have those two added up to 2, 4+2=6
True.
