Coordinate dilations are important for several reasons.

Computer programmers and graphics designers use coordinate dilations to animate and design digital images on the computer screen.

Structural engineers and draftsmen use dilations to generate images with computer-assisted design software in order to construct useful objects.

You can also use dilations to enlarge or reduce graphs of data.

Regardless of the application, enlargements and reductions of figures represented on the coordinate plane can be very useful and help you solve meaningful, real-world problems.
