X and Y axes.
1. Check the numbers 2.Extend the range of the axes.
There are two common ways to graph circles: using a cartesian graph and using a polar graph. For a cartesian graph, there are two familiar axes x and y which are orthogonal to each other. The formula for a circle is "x^2 + y^2 = a constant". In a polar graph, there are no axes and all points are defined by their radius from the center point, and the angle of the direction the point lies from the center. In a polar coordinate system, a circle is simply "r = a constant".
On your graph paper, after you draw and number the 'x' and 'y' axes, draw a straight linethat goes through the point [ y = 2 ] on the y-axis, and has a slope of [ 0.5 ).
The point in a Cartesian coordinate system where the axes intersect. On a 2-D graph, for example, this is where x and y equal zero. also the point (0,0) on a graph

A rectangle has 2 axes of symmetry.
Select two axes in a 2-d plane along which you want the vector components (3 axes in 3-d and so on). The axes must meet at a point, but need not be perpendicular.In 2-d, draw a parallelogram so that its diagonal is the given vector and the adjacent sides are parallel to the axes. These adjacent sides will represent the components of the vector.If the axes are at right angles and the vector Vmakes an angle t with the positive horizontal axis, thenhorizontal component = V*costandvertical component = V*sint

2 axes from angles to angles
A break in the axes is the most common method. Pictograms scaled on 2-dimensions (area) but using pictures of 3-d objects.

In the same coordinate space, i.e. on the same set of axes: -- Graph the first equation. -- Graph the second equation. -- Graph the third equation. . . -- Rinse and repeat for each equation in the system. -- Visually examine the graphs to find the points (2-dimension graph) or lines (3-dimension graph) where all of the individual graphs intersect. Since those points or lines lie on the graph of each individual graph, they are the solution to the entire system of equations.
