Average of the endpoints
If by sperical triangle you mean a triangle on the surface of a sphere, you will need 3 dimensional coordinate geometry. Whether you use polar coordinates or linear coordinates will depend on what you want to "solve".
If you mean end point A is (3, 5) and midpoint of line AB is (-2, 8) then end point B is (-7, 11)
Plot straight line or curved graphs on the Cartesian plane Plot a line of 'best fit' for any correlation of given data Solve simultaneous equations when the coordinates intersect each other Transformations
A linear system just means it's a line. A solution is just a point that is on that line. It means that the two coordinates of the point solve the equation that makes the line. Alternatively, it could mean there are 2 (or more) lines and the point is where they intersect; meaning its coordinates solve both (or all) equations that make the lines.

You can either measure or estimate the coordinates visually from the graph, or solve the equation underlying the graph.
Some problems are easier to solve using polar coordinates, others using Cartesian coordinates.

substitute 0 for y and solve for x. then substitute x for 0 and solve for why and you have the x and y coordinates
Select any value for one of the variables in the graph and solve the equation to get the other variable.

The formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle.
A linear system just means it's a line. A solution is just a point that is on that line. It means that the two coordinates of the point solve the equation that makes the line. Alternatively, it could mean there are 2 (or more) lines and the point is where they intersect; meaning its coordinates solve both (or all) equations that make the lines.
1.Finding the solution to a system of linear equations can be found using cartesian coordinates. 2. Graph a circle and you can find the radius using cartesian coordinates.
