Answer:
it is D hope this helps
Step-by-step explanation:
Answer: 100$.
100% - 80% = 20%
20$ / 0.20(20%) =100$
It’s the first one! The table shows X going up and Y going down, so the slope would be negative!
The slope is 1
Difference between the first and second y is 8
Difference between the first and second x is also 8
(8,8) simplifies to 1
Hope this helps!
