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.

Explore slope-intercept form of linear equations with Khan Academy's interactive lessons and practice exercises.

Learn how to find the slope-intercept equation of a line from two points on that line. If you haven't read it yet, you might want to start with our introduction to slope-intercept form.

Point-slope is the general form y-y₁=m (x-x₁) for linear equations. It emphasizes the slope of the line and a point on the line (that is not the y-intercept). We can rewrite an equation in point-slope form to be in …

When we have a linear equation in slope-intercept form, we can quickly find the slope and y -intercept of the corresponding line. This also allows us to graph it.

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.

Given two points on a line, we can write an equation for that line by finding the slope between those points, then solving for the y-intercept in the slope-intercept equation y=mx+b.

So the way that it's written right now, this is slope intercept form. It's written in the form Y is equal to mx plus b, where m in this case is 2/3 and b is 4/7.

So you might already recognize, this is in slope intercept form. Just as a reminder, slope intercept form is y is equal to mx plus b, where the coefficient on this x term right over here, that is our slope, and …

Slope intercept form is y=mx+b, where m is slope and b is the y-intercept. We can use this form of a linear equation to draw the graph of that equation on the x-y coordinate plane.
