êABC has coordinates A(-3, 1), B(1, 2) and C(-1, 4).

Write the coordinates of the image in matrix form.

a translation 2 units left and 3 units down?

Answer 1

when you say matrix form, do you mean putting the points in a 2x3 matrix? just put one point in each row. for the translation, left is in the negative direction, so you have to subtract it from the x values, and down in also in the negative direction, so you would also have to subtract three from the y values

Answer 2

yes, it must be in matrix form

Answer 3

okay. The matrix would be like this, correct?:\[\left[\begin{matrix}-3 & 1 \\ 1 & 2\\-1&4\end{matrix}\right]\]

Answer 4

it doesn't look like that's a choice
