  • Using slope formula
  • Determining if a slope is positive, negative, zero, or undefined
  • Writing equations of lines in y=mx+b form given the slope and y-intercept
  • Graphing lines given 2 points
  • Graphing lines in y=mx+b form
  • Identifying y-intercepts
  • Understanding that parallel lines have the same slope
  • Understanding that perpendicular lines have "opposite reciprocal" slopes
  • Vertical & horizontal lines
