Start with the point-slope formula shown at the top in red.

Now, substitute your slope and coordinates in the formula.

Then distribute and combine lie terms.

Finally, add 2x to both sides to get your equation in standard form.

The elements of Matrix C are shown below.

sergeinik [125]

The matrix that represents the matrix D is $\left[\begin{array}{cccc}3&1&-9&8\\2&2&0&5\\16&1&-3&11\end{array}\right]$

<h3>How to determine the matrix d?</h3>

Given the elements of the matrix C.

The matrix c is represented by its rows and columns element, and the arrangements are:

C11 = 3 C12 = 1 C13=-9 C14 = 8

C21 = 2 C22=2 C23 =0 C24 = 5

C31 = 16 C32 = 1 C33=-3 C34=11

Remove the matrix name and position

3 1 9 8

2 2 0 5

16 1 -3 11

Represent properly as a matrix:

$C = \left[\begin{array}{cccc}3&1&-9&8\\2&2&0&5\\16&1&-3&11\end{array}\right]$

Matrix C equals matrix D.

So, we have:

$D = \left[\begin{array}{cccc}3&1&-9&8\\2&2&0&5\\16&1&-3&11\end{array}\right]$

Hence, the matrix that represents matrix D is $\left[\begin{array}{cccc}3&1&-9&8\\2&2&0&5\\16&1&-3&11\end{array}\right]$
