The accompanying data represent x = amount of catalyst added to accelerate a chemical reaction and y 5 resulting reaction time:

x	1	2	3	4	5
y	49	46	41	34	25

a. Calculate r. Does the value of r suggest a strong linear relationship?

b. Construct a scatterplot. From the plot, does the word linear provide the most effective description of the relationship between x and y? Explain.
