Apply the trial and error method and find the value of (x, y) up to three pairs, which satisfy the linear equation.Make sure the linear equation is in y-intercept form, which is y = mx + b.The following steps are to be taken up for plotting a linear equation with one variable: Hence, it is advised to plot one more point to ensure that the solutions obtained for the given linear equation are correct. However, we cannot find out if there are any mistakes in obtaining these values as the two points can always be joined and represented as a line. While plotting the equation on a graph, the two pairs (x,y) are sufficient. Graphing a linear equation is about solving the linear equations and representing the solution in a coordinate plane. The point where any line crosses the y-axis on the graph - Y-Intercept.The point where any line crosses the x-axis on the graph - X-intercept.The graphing of linear equations helps in solving many real-life problems in linear programming. The graph of a linear equation in one variable x forms a vertical line that is parallel to the y-axis and vice-versa, whereas, the graph of a linear equation in two variables x and y forms a straight line. Similarly, all linear equations create a straight line on the graph with both one or two variables. Here, the equation x+2y=7 makes a straight line on the graph.
We have to represent the equation x+2y=7 in a graph. Let us see an example of graphing a linear equation with one variable.
The representation of a linear equation on a graph is called graphing linear equations shown as a straight line with one or two variables. We represent the linear equation in y=mx+b form, also known as the y-intercept form. Linear equations are algebraic equations in which each term has a real constant and the equation contains 2 variables of the highest power 1.
