Ascatter plot is made to model the amount of money left to pay on a mortgage. the data used for the scatter plot are shown in the table
number of months money owed
3 114,000
5 100,000
1 118,000
2 116,000
0 120,000
4 112,000
what does the y intercept of the model represent?
the amount of the mortgage that has been paid that month
the monthly payments
the original amount of the mortgage
the number of months it takes to pay off the mortgage

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.
