The z-direction is used in upper level mathematics when the additional variable, z, is added for analysis. When this is done, equations are usually functions of x and y, with z being the dependent variable. Functions in the x-y plane are a special subset of the functions with x, y, and z, where z = 0.
Algebra, Calculus and other lower math courses typically only deal with the two variables, x and y, because, as many people will attest, it is hard enough just with two variables. Therefore it is enough for all the graphs to be contained in the x-y plane and to ignore the z-direction in order for students to learn basic concepts and ideas to be used in later math courses which may add the z variable (and potentially more variables in the more abstract math courses).

What is planner graph?
In graph theory, a planar graph is a graph that can be embedded in the plane, i.e., it can be drawn on the plane in such a way that its edges intersect only at their endpoints. In other words, it can be drawn in such a way that no edges cross each other.A planar graph already drawn in the plane without edge intersections is called a plane graph or planar embedding of the graph. A plane graph can be defined as a planar graph with a mapping from every node to a point in 2D space, and from every edge to a plane curve, such that the extreme points of each curve are the points mapped from its end nodes, and all curves are disjoint except on their extreme points. Plane graphs can be encoded by combinatorial maps.Example of Planner graphButterfly Graph.
What are coplanear lines?
Coplanar lines are 2 or more lines located on the same plane. Ex.: If you draw 2 or more lines on a graph, they are all coplanar (the plane they are all on is the piece of paper you drew the graph on).
An equation where the graph of all solutions lies on a line?
If it is a straight line, then the equation is linear.
What type of intersections happen between lines and planes?
A line that does not lie within a plane and intersects the plane does so at one point.A line that lies within a plane intersects the plane at all points.
Does 3 4 point lies on 2x plus 4?
if your point if 3/4 and your line is y=2x+4 then yes 3/4 does lie on this graph. any point in existence lies on this graph because its domain is all real numbers
What is an equation where the graph of all solutions lies on a line?
There are an infinite number of equations that meet that requirement. One of them is y = x
What planet lies in its orbit plane?
All planets lie in the plane of their orbit, but most spin on an that is nearly (many have tilted axes of spin) perpendicular to that plane. The one exception is the planet Uranus which has its axis of spin lying very close to its orbital plane.
What is a quadrant 2?
Quadrant II (Quadrant 2) is the region of the coordinate plane (xy-plane, a graph) that is above the x-axis and to the left of the y-axis. In this quadrant, all x values are positive and all y values are negative.
How do you make a circle graph?
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".
What is subgraph in given graph?
If all the vertices and edges of a graph A are in graph B then graph A is a sub graph of B.
How do you graph functions?
Suppose a function takes values of a variable, X, as its input, and that it converts it into an output value Y.Then the graph of the function, in the X-Y coordinate plane, is the set of all points (x, y) such that when you input the value x into the function, the output is y.Suppose a function takes values of a variable, X, as its input, and that it converts it into an output value Y.Then the graph of the function, in the X-Y coordinate plane, is the set of all points (x, y) such that when you input the value x into the function, the output is y.Suppose a function takes values of a variable, X, as its input, and that it converts it into an output value Y.Then the graph of the function, in the X-Y coordinate plane, is the set of all points (x, y) such that when you input the value x into the function, the output is y.Suppose a function takes values of a variable, X, as its input, and that it converts it into an output value Y.Then the graph of the function, in the X-Y coordinate plane, is the set of all points (x, y) such that when you input the value x into the function, the output is y.
