Please help Show some kind of work I don’t want to get it wrong!!! Solve each system by substitution.
9) y=-2
-6x + 7y=-8
A) (-8,-2)
C) (-1,-2)
B) (-3,-2)
D) (1, -2)

square root

step-by-step explanation:

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.
