In general, a linear equation CANNOT be made to go through three points. That will only happen if the three points are collinear and in that case, the equation of the line will only require two points.

A linear equation in three variable.
It is a linear equation in three variables which is equivalent to a linear equation in two variables. This is because 3 + e = 2.3f +e - 7g is equivalent to 3 = 2.3f -7g
Calculate the coordinates of three points, and plot the points on the graph. Draw a straight line through them.To calculate the coordinates, assign any value for "x", replace in the equation, and solve for "y".Note that two points are enough in theory; the third is for additional verification, in case you commit some mistake.
There are no disadvantages. There are three main ways to solve linear equations which are: substitution, graphing, and elimination. The method that is most appropriate can be found by looking at the equation.
No, they are simply three expressions: there is no equation - linear or otherwise.
Single answer. Coincidental (same equation), No solution.

In question and answer logic answers are given and if they fall in an area bounded by the inequality then it is a good answer. After graphing three or more inequalities the vertexes are the possible maxima of the system of equations.
A linear system is an equation to find the intersection of two or more lines. The equations are usually expressed with two variables, x and y. I don't know yet, but maybe geometry might have three variables, including z. Basically it's where two lines intersect and the most common ways of solving it are through graphing, substitution, and/or elimination.Presume you mean "linear".These are systems whose parameters vary directly or proportionally. Plotting functions results in straight lines.
That may be, but a single linear equation in three unknown variables cannot be solved.
The general technique for graphing quadratics is the same as for graphing linear equations. However, since quadratics graph as curvy lines (called "parabolas"), rather than the straight lines generated by linear equations, there are some additional considerations.The most basic quadratic is y = x2. When you graphed straight lines, you only needed two points to graph your line, though you generally plotted three or more points just to be on the safe side. However, three points will almost certainly not be enough points for graphing a quadratic, at least not until you are very experienced. For example, suppose a student computes these three points:Then, based only on his experience with linear graphs, he tries to put a straight line through the points.
