The triangle is illustrated below.
<h3>How to explain the triangle?</h3>The first thing you should find are the new vertices:
(x, y) ---> (2x, 2y) ---> (x', y')
(0, 0) ---> (2 (0), 2 (0)) ---> (0, 0)
(-4, 4) ---> (2 (-4), 2 (4)) ---> (-8, 8)
(-4, -2) ---> (2 (-4), 2 (-2)) ---> (-8, -4)
Then, you must join the ordered pairs and graph the new triangle.
See the attached graph.

Answer:
The determinant is 15.
Step-by-step explanation:
You need to calculate the determinant of the given matrix.
1. Subtract column 3 multiplied by 3 from column 1 (C1=C1−(3)C3):
2. Subtract column 3 multiplied by 3 from column 2 (C2=C2−(3)C3):
3. Expand along the row 2: (See attached picture).
We get that the answer is 15. The determinant is 15.
