What is the correlation coefficient with the following data points: (2,26), (3,2), (5,16)

The correlation coefficient is -0.2353 or about -0.24

Step-by-step explanation:

use the eqn below to calculate the corr coeff:

r=--0.24

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

step-by-step explanation:

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
