The point (1, 0) is on a circle, which center is on the line y = -2x. The line 3x + 4y + 15 = 0 is a tangent to the circle. Find the equation(s) for the circle(s).
Thanks,

Analytical geometry is a branch of mathematics that combines algebra and geometry to study geometric shapes and their properties using coordinate systems and equations.
The key concepts in analytical geometry include points, lines, curves, and surfaces in a coordinate system, as well as concepts such as slope, distance, and the equations that represent these shapes.
Analytical geometry is used in various fields such as engineering, physics, computer graphics, and navigation. It is used to model and analyze real-world problems, design structures and machines, and create visual representations of data.
Some common equations used in analytical geometry include the equation of a line (y=mx+b), the distance formula (d=√((x2-x1)^2+(y2-y1)^2)), and the equation of a circle ((x-h)^2+(y-k)^2=r^2).
To improve your understanding of analytical geometry, you can practice solving problems, work on visualizing and interpreting geometric shapes, and study the key concepts and equations. It can also be helpful to seek out additional resources such as textbooks, online tutorials, and practice exercises.
