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 …

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.

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.

Find the equation of this line in point slope form, slope intercept form, standard form. And the way to think about these, these are just three different ways of writing the same equation.

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.

Point-slope form: y-a = m (x-b). For example, your slope (m) is 3 and your point (a,b) is 9,10. You would substitute your y-coordinate for a, and your x- coordinate for b. Your new equation would look like …

Walk through a graphical explanation of how to find the slope from two points and what it means.

Learn how to write an equation in slope-intercept form (y=mx+b) for the line with a slope of -3/4 that goes through the point (0,8). We identify the slope (m) and y-intercept (b) to create our equation y = ( …

With Point-slope form you can graph a line knowing any point and the slope. With slope-intercept form, you need the y-intercept (not just any point) to get the line.

Learn how to graph lines whose equations are given in the slope-intercept form y=mx+b. If you haven't read it yet, you might want to start with our introduction to slope-intercept form.
