Question

The coordinates of the vertices of triangle ABC are A(-3,1), B(0,5), and C(-2,-3). What are the coordinates of the vertices of the transformed image using (3x, 4y)? A С" В' Answer:

Answer 1

We have a triangle with vertexes A(-3,1), B(0,5) and C(-2,-3) and we have to fin the new points given by the trasformation (3x,4y). This means that we have to multiply the x component by 3 and the y component by 4.

Then, the new points are

$\begin{gathered} A^{\prime}(-9,4) \\ B^{\prime}(0,20) \\ C^{\prime}(-6,-12) \end{gathered}$
