For most equations you simply need to plot a few points on the graph by plugging in inputs and generating outputs Then you can draw a line through the points Each input represents a position on the X axis while each output is positioned somewhere along the Y axis Introduction Can you solve the equation log 2 x 4 3 x Would any of the algebraic techniques you ve learned so far work for this equation Try as you may you will find that solving log 2 x 4 3 x algebraically is a difficult task

Graph a linear equation by plotting points Step 1 Find three points whose coordinates are solutions to the equation Organize them in a table Step 2 Plot the points on a rectangular coordinate system Check that the points line up If they do not carefully check your work Step 3 Draw the line through the points To graph a linear equation start by making sure the equation is in y mx b form Then plot the b value on the y axis Next convert the m value into a fraction if it s not already by placing it over 1 Once you ve done that start at the point you plotted on the y axis and count up the number that s in the numerator of the fraction
Step 1 Analyze what form each equation of the system is in Step 2 Graph the equations using the slope and y intercept or using the x and y intercepts Case 1 If the equations are in the slope intercept form identify the slope and y intercept and graph them Explore math with our beautiful free online graphing calculator Graph functions plot points visualize algebraic equations add sliders animate graphs and more
