Answer:
Reflection; L (-7, -5)
Explanation:
For background knowledge if you don't know:
Translation : Moving to the left, right, up, or down. When you make a translation, the shape will be the same size and the points will face the same direction but the shape will be in a different quadrant or area of the coordinate plane.
Reflection : Think of it like a mirror. When you look into a mirror, you see yourself, but everything is the opposite. When a shape is reflected on a coordinate plane, the qualities of it haven't changed but it will usually look like the opposite, similar to this photo. Think of the shape as you, and the lines of the coordinate plane as a mirror.
Rotation : Think of this like rotating a device's screen or your head a different way. The qualities of the shape will still be the same, but the shape will be rotated at a different angle. For example, lets say the shape you had on the coordinate plane was a rhombus. It rotated on the coordinate plane and now it looks similar to a square. If you rotate a shape, it will just be at a different angle, the exact same qualities.
Dilation : Think of it like magnifying a picture on your screen. When you magnify something, you make it look larger. When you minimize something, it becomes smaller. This is the exact same thing with dilation. the shape will have the same exact qualities in the same exact spot, but just a different size.
This answer is a reflection because it has the same exact qualities, but just bounces off of the x-axis and reflects onto the 3rd quadrant.
