How to Graph a Line
How to graph a line in slope-intercept formSteps:
Plot the y-intercept (b) on the y-axis. Use the slope to find more points on the line. Connect the dots! |
How to graph a line in standard formSteps:
Use A,B,and C to find the x-intercept, y-intercept, and slope. C/A = x-intercept C/B = y-intercept -A/B = slope Graph the x-intercept on the x-axis. Graph the y-intercept on the y-axis. Use the slope to get more points on the line. Connect the dots! Alternate steps: Rearrange standard form to slope-intercept form by solving for y. Then follow the steps for graphing a line in slope-intercept form. |
How to graph a line in point-slope formSteps:
Plot the point given. Use the slope to find more points on the line. Connect the dots! |
How to graph a horizontal lineSteps:
Go up or down on the y-axis to find the number given. Draw a horizontal line across the graph at that number. Horizontal lines have a slope of zero. |
How to graph a vertical lineSteps:
Go left or right on the x-axis to find the number given. Draw a vertical line up and down on the graph at the number. Vertical lines have an undefined slope. Vertical lines are not functions. |
