On a coordinate plane, parallelogram P Q R S is shown. Point P is at (5, 1), point Q is at (6, 4), point R is at (3, 10), and point S is at (2, 7). Which statement proves that PQRS is a parallelogram? The slopes of SP and RQ are both –2 and SP = RQ = StartRoot 45 EndRoot. The slopes of RS and QP are both 3 and SP = RQ = StartRoot 45 EndRoot. The midpoint of RP is (4, 5 and one-half) and the slope of RP is Negative nine-halves. The midpoint of SQ is (4, 5 and one-half) and SQ = 5.

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.
