Answer:

c)
Step-by-step explanation:
the x rate of change is +2 and the y rate of change if -1. slope is always y over x, therefore, do exactly that. put y (-1) over x (2). thus gett in your answer of the slope.
The answer to this question is A
Answer: because they were right for each other.
Step-by-step explanation:
Answer : 60 degrees
Explanation: All triangles's angles add up to 180. Since all angles are equal, you can divide 180 by 3. 180/3 is 60
Slope intercept = y=mx+b
m is the slope
b is the y int
point slope =y2-y1=m(x1-x2)
