More Lessons for Grade 7
Videos, worksheets, stories and songs to help Grade 7 students learn to graph lines by x and y-intercepts.
How to graph a line using the x and y intercepts?
1. The x-intercept is the point on the graph where the line crosses the x-axis. To find the x-intercept replace y with 0 in the equation and solve for x.
2. The y-intercept is the point on the graph where the line crosses the x-axis. To find the y-intercept replace x with 0 in the equation and solve for y.
3. Plot the x-intercept and the y-intercept.
4. Join the two points with a line to form the graph.
Graphing Lines using the x-intercept and y-intercept
How to find the x and y intercepts of a line, and how to plot those points to graph the line.
Shows more examples of how to graph lines by making a table or chart of ordered pairs, or using the x and y intercept method. It also shows how to decide which method is easiest for a given equation.
Graphing Lines Using Intercepts
Learn to graph a given linear equation using the intercept method. The x-intercept is the point on the graph where the line crosses the x-axis, so the x-intercept will always have a y-coordinate of 0, and the y-intercept is the point on the graph where the line crosses the y-axis, so the y-intercept will always have an x-coordinate of 0.
