if you're talking about the whole number, 100.96. if you're referring to decimal place values; 96.70.

underline the digit that you round to

circle the digit to the right

five or more goes up

four or less stays the same

everything behind becomes a zero.

Use a matrix to find the coordinates of the endpoints or vertices of the image of each figure under the given reflection.

The vertices of the original quadrilateral can be written in matrix form using the vertex matrix. The vertex matrix is
$\begin{pmatrix}-5&-1&-3&-7\\ 4&-1&-6&-3\end{pmatrix}$

To find the coordinates of the endpoints or vertices of the image of the given coordinate points reflected about the y-axis, we just need to multiply the transformation matrix by the vertex matrix. The transformation matrix for this particular problem is
$\begin{pmatrix}-1&0\\ 0&1\end{pmatrix}$

Multiplying the two matrices, we have
$\begin{pmatrix}-1&0\\ 0&1\end{pmatrix}\begin{pmatrix}-5&-1&-3&-7\\ 4&-1&-6&-3\end{pmatrix}=\begin{pmatrix}5&1&3&7\\ 4&-1&-6&-3\end{pmatrix}$

Therefore, the coordinates of the endpoints or vertices of the image are (5,4), (1,-1), (3, -6) and (7, -3).

let us assume that make inclination θ

with positive direction of x-axis then slope(m) of the line is given by

m=tanθ.
