Question 965542: Can someone please help with this - I have submitted it a couple of days in a row - Please help
A model of the linear relationship between variables x and y is given by the regression equation ŷ = 3.5 + 0.8x.
1) What, if anything, can be determined about the value of r, the correlation between x and y? Why?
2) Graph the regression line on the axes when the value of x = 15.

The regression gives you the correlation by the coefficient of x
which is 0.8
