In a linear equation, the x-intercept is really just the point where the graph of the line crosses the x-axis.

Find the x and y intercepts in a given linear equation written in slope intercept form. Piece of cake! There are just two things to do. First, substitute 0 for x and solve to find the y-value. Then substitute 0 for y to find the value of...

The x-intercept is the point at which the line of the equation crosses the x-axis. The y-intercept is the point at which the line of the same equation crosses the y-axis. It's as easy as that. Look at your graph and note these locations.

An equation can be gotten from the graph of a line. Yes, it can. Watch this video and follow the instructor as she goes step-by-step explaining and illustrating how to get an equation from information from the graph of a line.

The x-intercept is the point at which the line of the equation crosses the x-axis. The y-intercept is the point at which the line of the same equation crosses the y-axis. It's as easy as that. Look at your graph and note these locations.
