The new coordinates are (-1, 7), (-3, 3) and (-8, 5)
Step-by-step explanation:
To get the new coordinates after the translation, we will first find the initial coordinates of the three vertices
The three vertices: (3, 3), (1, -1) and (-4, 1)
A translation of 4 units to the left:
A translation of 4 units up:
Plotting the points:
