Which best describes the diameter of a circle?
<em>Statements</em>
<u><em>A. The distance from the center to any point of the circle</em></u>
This statement describes the radius of the circle
<u><em>B. The length of a chord that contains the center of the circle</em></u>
This statement describes the diameter of the circle
<u><em>C. The distance around the circle</em></u>
This statement describes the circumference of the circle
<u><em>D. The length of a chord that does not contain the center of the circle</em></u>
This statement describes a line segment linking any two points on a circle that does not contain the center of the circle
therefore
<u>the answer is the option</u>
B. The length of a chord that contains the center of the circle
A function is a relationship where each x-value is paired with exactly one y-value.
When looking at a graph, you want to ask yourself, "Can I find any two points on this graph that have the same x-value?"
I can see with x=8 that there would be two points on that graph with an x-value of 8, making this not a function.
People call this test "the vertical line test" because any vertical line really represents a single x-value. If any vertical line hits the graph more than once, the graph cannot be a function, because that value of x has more than one y-value.

Step-by-step explanation:
-3x - 3y = 3 ⇒ -3x - 3y = 3
5x + 1y = -17 ⇒ <u>-15x - 3y = 51</u>
<u>12x</u> = <u>-48</u>
12 12
x = -4
5x + y = -17
5(-4) + y = -17
-20 + y = -17
<u>+ 20 + 20</u>
y = 3
(x, y) = (-4, 3)
