To find the new coordinates of point C after the translation, we start with the coordinates of C, which is given as \( C(-5, 1) \).
The translation specified is:
- Horizontally by \(-4\): This means we will subtract 4 from the x-coordinate.
- Vertically by \(+3\): This means we will add 3 to the y-coordinate.
Now, we apply the translation to the coordinates of point C:
-
For the x-coordinate: \[ -5 - 4 = -9 \]
-
For the y-coordinate: \[ 1 + 3 = 4 \]
After performing the translation, the coordinates of point \( C' \) will be \((-9, 4)\).
Therefore, the coordinates of \( C' \) are \((-9, 4)\).
