It going down starting from the left to right . Positive would be the other way around and zero would be side to side while undefined would be an up and down line .
Answer:
D m = -1
Step-by-step explanation:
To find the slope of the line
m = (y2-y1)/(x2-x1)
= (-12--11) / (10-9)
= (-12+11) / (10-9)
= -1/1
= -1
