7.5 Systems Of Inequalities

  1. 1. Algebra Warm up; pg. 352 # 66 to 73 Remember--they must be in Slope intercept form to determine if they are parallel (same slope) or perpendicular (opposite signs and recipricals)
  2. 2. 7.5 Systems of Inequalities pg. 345 to 352 Linear inequality-- Looks like Linear equation BUT has inequality! In the past you graphed them on a number line NOW- Becasue you have an x and a y They are graphed on coordinate planes! They are now lines that are considered boundry lines. WHY? Becasue now you also have to shade the graph!
