Graph your problem using the following steps Type in your equation like y 2x 1 If you have a second equation use a semicolon like y 2x 1 y x 3 Press Calculate it to graph Free online graphing calculator graph functions conics and inequalities interactively
Solve for y then graph a linear equation The linear equations we have graphed so far are in the form y mx b where m and b are real numbers In this section we will graph linear equations that appear in different forms than we have seen Graph y 3x and y 3 in the same rectangular coordinate system Solution We notice that the first equation has the variable x while the second does not We make a table of points for each equation and then graph the lines The two graphs are shown

The following diagrams show the different methods to graph a linear equation Scroll down the page for more examples and solutions In these lessons we will learn how to graph linear equations by plotting points Click here how to graph linear equations by finding the x intercept and y intercept Click here Sketch the graph of y frac 1 3 x 3 Solution The equation y frac 1 3 x 3 has the form y mx b Therefore the equation is linear and the graph will be a line Because two points determine a line we need only find two points that satisfy the equation y 1 3x 3 plot them then draw a line through them with a ruler
There are three ways you can graph linear equations 1 you can find two points 2 you can use the y intercept and the slope or 3 you can use the x and y intercepts In the following guide we will look at all three Socratic questions how do you solve the system of equations y 1 3x 3 and 2x y 4 by graphing The answers are displaystyle x 3 and displaystyle y 2 Explanation To solve a system of equations by graphing graph the two individuals equations and find their intersection
