We previously wrote the equation for a linear function from a graph. Now we can extend what we know about graphing linear functions to analyze graphs a little more closely. Begin by taking a look at the graph below. We can see right away that the graph crosses the y-axis at the point (0, 4), so this is the y-intercept.
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.
In the previous unit, Graphing Equations you learned how to graph linear equations on a coordinate grid. In this unit, we are going to reverse that process and write equations to match a graph or a word problem. This unit is very important, because in many real life situations, you will not be given an equation to solve.
The procedure to use the graphing linear equations calculator is as follows: Step 1: Enter the linear equation in the input field Step 2: Now click the button “Submit” to get the graph Step 3: Finally, the graph of the given linear equation will be displayed in the new window.

Writing Equation from Table of Values. Often, students are asked to write the equation of a line from a table of values. To solve this kind of problem, simply chose any 2 points on the table and follow the normal steps for writing the equation of a line from 2 points. Problem 4. Original problem; Step 1; Step 2; Step 3; Step 4
