Find the image of the `(-2,-7)` under the transformations (x,y) to `(x-2y,-3x+y).`

Explanation

To find the image of the point \((-2, -7)\) under the transformation defined by the equations \( (x, y) \to (x - 2y, -3x + y) \), we will follow these steps:

### Step 1: Define the transformation
Let the image of the point \((x, y)\) be denoted as \((x_1, y_1)\). According to the transformation, we have:
\[ x_1 = x - 2y \]
\[
