Help stuck on this question

1.  neither

2. perpendicular

3. neither

4. parallel

Step-by-step explanation:

Remember:   Parallel lines have the same slope and the slope of perpendicular line are negative reciprocals of each other.    Also the slope is the coefficient of the x-term

1.  neither                    

2. perpendicular                            

3. neither

4. parallel

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent

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.
