Regression equation:
y=
Correlation coefficient:

Step-by-step explanation:

The equation of the line of best fit is y = -4.75x + 88.571 and the correlation coefficient r is -0.906.

y = ax + b    

a = -4.75

b = -88.571  

r² = 0.821  

r = -0.906

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
