Writing lines (linear equations) in Standard Form is a must know skill for algebra students. Often times we see lines in y = mx + b form (example y= 3x + 7) and this is good if we want to graph a line using the slope-intercept method. However a line in Standard Form ( Ax + By = C example 3x + 4y= 12 )is easy to graph using the x and y intercept method.
* lines can be written in slope-intercept or standard form
* graphing lines in standard form is easy by finding the x and y intercepts
some key topics that involve writing lines in standard form:
* using the point-slope formula
* slope-intercept formula
* linear word models
