Section 5.3/5.4: (Writing) Slope Intercept Form
The slope-intercept form is one way to write a linear equation (the equation of a line). The slope-intercept form is written as y = mx+b, where m is the slope and b is the y-intercept (the point where the line crosses the y-axis). It's usually easy to graph a line using y=mx+b. Other forms of linear equations are the standard form and the point-slope form.
When given an equation in the form y = mx + b, or slope-intercept form, we should know how to graph a line without having to compute two points on it. If we have an equation in slope-intercept form, we automatically know the slope and the y-intercept and can use that information to more quickly and efficiently graph the line. Another method of graphing a line is using a table of values or the intercepts.
