2. Label the type of Correlation based on the Correlation coefficient (r values) below. Be specific and explain your reasoning when necessary.
r= -0.11
r= -0.87
r=0.28
r=0.98

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
