select the sentence that explains the error in the given statement.

a line is contained in exactly one plane

a. a line must be coplanar to be contained in exactly one plane.
b. a line cannot be contained in a plane.
c. a line is contained in exactly one point.
d. a line can be contained in more than one plane.

D. A line can be contained in more than one plane .

Step-by-step explanation:

A. is wrong because a line can't be said as coplanar . We can draw infinite number of planes through a line .

B. is wrong because a line can be contained in infinite number of planes.

C. is wrong because a line can't be contained in a point as a line is a collection of points.

D. is the right answer as every line passes through infinite number of planes.

if you mean

then it's c. 8, -7/3

but if you mean

then it is

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1
