Question

The coordinates of a triangle are (2, 3), (3, 1), and (4, 5). Find the coordinates of thetranslated triangle if it is enlarged by a scale factor of 3.

Answer 1

`(6,9),(9,1),(12,15)`

Explanation:

To calculate the new coordinates we must multiply each point by the scale factor, just like this:

`\begin{gathered} (2,3)\rightarrow(3\cdot2,3\cdot3)\rightarrow(6,9) \\ (3,1)\rightarrow(3\cdot3,3\cdot1)\rightarrow(9,1) \\ (4,5)\rightarrow(3\cdot4,3\cdot5)\rightarrow(12,15) \end{gathered}`
