If it is a straight line, then the equation is linear.
It represents all solutions to the linear equation.
A single equation in two variables is, for example. Its graph is a line, and every point on the line is a solution.
The graph will be a line.
In graph form, the linear equation lies below the true line or curve.
When it is a linear equation.
You'll need another equation to solve this one. The equation you give has a graph that is a line. Every point on the line is a solution to the equation so there are infinitely many solutions.
The graph is a line that you can't see because it lies entirely on the x-axis.The equation of the line is: Y=0
To find the solutions.
The intersection of the individual graphs. In the simplest case, the graph for each equation consists of a line (or some curve); the intersection is the points where the lines or curves meet.
