Linear Equations in Two Variables. Equations of degree one and having two variables are known as linear equations in two variables. It is of the form, ax +by +c = 0, where a, b and c are real numbers, and both a and b not equal to zero. Equations of the form ax+by = 0; where a and b are real numbers, and a,b ≠ 0, is also linear equations in two variable.
Graphing Linear Equation: Type 3. To graph a linear equation, first make a table of values. Assume your own values for x for all worksheets provided here. Substitute the x values of the equation to find the values of y. Complete the tables, plot the points, and graph the lines.
For the equation, complete the table for the given values of x. Using the information from the table, graph the line of the equations on the coordinate plane below. Be sure to plot all points from the table and draw a line connecting the points.
In linear functions, there are two concepts: slope and intercept. The shape of the graph will change depending on what number of slopes and intercepts are used. Linear functions also require us to write graphs and create linear equations from them.
Standard form is great for finding the x and y intercepts of a graph, that is, the point where the graph crosses the x-axis and the point where it crosses the y-axis. Also, when solving systems of equations -- finding the point where two or more functions intersect -- the equations are often written in standard form.
