Which of the following graphs shows a negative linear relationship with a correlation coefficient, r, close to -0.5?
A. Graph A
B. Graph B
C. Graph C
D. Graph D

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8

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.

step-by-step explanation:

nope.   happens to me as well.
