What is the equation of the parabola with vertex (6,7) and focus (7,7)?
1 answer:
Answer:
Step-by-step explanation:
If you plot these points on a coordinate plane, you see that they are on the same horizontal line, y = 7, with the focus 1 unit to the right of the vertex. This means that the parabola is a sideways opening parabola, to the right, to be more specific. That means that it has the basic vertex form
where p is the distance in units from the vertex to the focus, h is the first coordinate in the vertex, and k is the second coordinate in the vertex. For us, p = 1, h = 6, and k = 7. Now we will just fill the vertex form of the equation in with our values:
We will solve this for x now by dividing each side by 4 and adding over the 6:

Answer:
Option B and C are correct.
are the expression incorrect for slope
Step-by-step explanation:
Slope is defined as the change in the dependent variable relative to the change in the dependent variable
or the ratio of the horizontal changes to vertical changes between any two points on the graph of the line.
The vertical changes between any two points is rise
The horizontal changes between any two points is run.
Formula for slope is given by:
For any two points and
then slope is:
or we can write this as:
Δy =
Δx =
⇒
Therefore, the expression which are incorrect for slope are;
Answer:
None
Step-by-step explanation:
Let’s graph the points first.
Look at the image below.
And by looking at the image we can tell that none of the points lay on the same horizontal line.
<em>Thus,</em>
<em>none of the points lay on the same horizontal line.</em>
