So now that we know what an x-intercept is, it's the point where a graph intersects the x-axis or intercepts the x-axis and the y-intercept is the point where a graph intercepts the y-axis or …

The x-intercept is the x value when y is equal to 0, or it's the x value where our graph actually intersects the x-axis. Notice right over here our y value is exactly 0.

The x-intercept of a line is the point at which the line crosses the x-axis. In other words, it’s the value of x when y equals zero in the equation of the line.

Slope-intercept form (y=mx+b) of linear equations highlights the slope (m) and the y-intercept (b) of a line. Watch this video to learn more about it and see some examples.

The x-intercept is where a line crosses the x-axis, and the y-intercept is the point where the line crosses the y-axis. Thinking about intercepts helps us graph linear equations.

Learn about the slope-intercept form of two-variable linear equations, and how to interpret it to find the slope and y-intercept of their line.
