Graphing Linear Equations in Slope-Intercept Form

Vocabulary

  • Slope-intercept form — A way to write linear equations as y=mx+by = mx + b, where mm is the slope and bb is the y-intercept.
  • Standard form — A way to write linear equations as Ax+By=CAx + By = C.
  • Slope — The steepness of a line, represented as “rise over run” in the video.
  • Y-intercept — The point where the line crosses the y-axis, represented as bb in the slope-intercept form.
