hello?

hi

OpenStudy (kropot72):

|dw:1456358873379:dw| I have drawn an estimated line of best fit. Can you estimate the value of r using the slope of the line?

OpenStudy (anonymous):

how do I know what the slope is

OpenStudy (kropot72):

Sorry, you need to do more than find the value of the slope. However the slope is negative, therefore r must be negative. I must log out now. Hopefully someone else can help further.
