Standard Form and Slope-Intercept Form

After this afternoon's fire drill, we looked at how equations are written. Those written in the form of y = 2x + 6 are said to be written in slope-intercept form. Mathematicians call this y = mx + b, where m stands for the slope of the line and b indicates where the y-intercept will be. When reporting the slope, write it as "m = " some number. When reporting the y-intercept, report this as an ordered pair (point).

Sometimes equations are written in the form of Ax + By = C or Ax + By + C = 0. This form of an equation is called the standard form of an equation. We explored how to change an equation from one form to another.
