Compare with the vertex form and get the answer.

#### Explanation:

The vertex form would be

We can write the given equation in the vertex form and get the vertex.

Now we have got it to a form which we can recognize.

Comparing with

The vertex is

**Alternate Method**.

*The alternate method is when you put #7x-2 =0# and solve for x to find #x= 2/7# and get x-coordinate of the vertex. When you substitute #x=2/7# in the given equation you would get #y=-7# which would be the y-coordinate of the vertex and still you would get the vertex #(2/7,-7)#*
