To find the resulting coordinates after applying the translation vector <-4, 8> to the original coordinates (-4, 7), we need to add the components of the translation vector to the corresponding components of the original coordinates.
The original coordinates are:
- \(x = -4\)
- \(y = 7\)
The translation vector components are:
- \(x\) component = -4
- \(y\) component = 8
Now, we calculate the new coordinates:
- New \(x\) coordinate: \[ -4 + (-4) = -4 - 4 = -8 \]
- New \(y\) coordinate: \[ 7 + 8 = 15 \]
Therefore, the resulting coordinates after the translation are \((-8, 15)\).
The correct answer is: a. (-8, 15)
