Answer 2

explain to her

Answer 3

For A) just jot down the matrix of the given triangle , then multiple it by 2
like this : M(-2,1), L(1,1), K(-2,5), then the matrix of it is
\[\left[\begin{matrix}-2&1&-2\\1&1&5\end{matrix}\right]\]
then the required matrix is
\[2*\left[\begin{matrix}-2&1&-2\\1&1&5\end{matrix}\right]=??\]

Answer 4

For B) since you have the new coordinates of the points, it is easy to draw out, right?

Answer 5

For C) do the same A with the factor is 1/2
