Answer:
17: A,C,B 18: C,A,B 19: A,C,B 20:A,C,B
Step-by-step explanation:
Slope(rate of change) can be found by dividing the change in y over the change in x. For example, #17 table, the change in y is (1-0)=1 and the change in x is (6-3)=3. Now, divide the to to get 1/3. Once you have all the rates of change you can list them in order.

Answer:
1/18
Step-by-step explanation:
-(-5/9) would turn into a positive 5/9. It cancels its own negative out.
The problem then turns to -1/2+5/9. Find the least common denominator and then combine.
Answer:
1. 3
2. -2
3. (1, 2)
Step-by-step explanation:
y axis is the numbered line that looks like the |
x axis is _
so the y int is 3 because A intercepts the y axis at 3
the y int for B is -2 because it intercepts the y axis at -2
the intersection of both lines is (1, 2) because you look and the point is at 1 for x and 2 for y
The numbers are 5, 6, 8, 12
