The slope of the graph is -1/2 using the rise over run method it rises up one and too the left twice so it would he -1/2
It is definitely C: 20%
Subtract the original value from the new value, then divide the result by the original value then multiply the result by 100 and it will give you the answer


The two numbers are 23 and 2
The answer is A. The graph is an X^2 graphed but when you add the negative it flips the graph over the y-axis.
