To translate a point in the Cartesian coordinate system, you adjust the coordinates based on the translation vector. Translating a point 5 units to the left means you will subtract 5 from the x-coordinate of the point.
Given the original point \( (-3, -2) \):
- The x-coordinate will change from -3 to \(-3 - 5\).
- The y-coordinate remains unchanged at -2.
Calculating the new coordinates:
- New x-coordinate: \( -3 - 5 = -8 \)
- New y-coordinate: \(-2\)
Therefore, the vertex of the triangle after the translation is \((-8, -2)\).
So, the point \((-3, -2)\) translated 5 units to the left becomes \((-8, -2)\).
