Describe and correct the error a student made in finding the midpoint of CD with C(-4,5) and D(-1,- 4).

Choose the correct answer below.

O A. The student used incorrect coordinates when calculating the midpoint.

O B. The student did not add the x- and y-coordinates when calculating the midpoint.

OC. The student did not divide the numerator and denominator by 2 when calculating the n

OD. The student swapped the x- and y-values when calculating the midpoint.

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.

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.
