1. ALGEBRA  9.19.19 Bellringer in GOFO!

2. Bellringer Write an equation to represent each situation. 1.  Notebooks cost $3 each and pencils are $2 a piece.  If Jordan has $75, how many of each could he purchase? 2.  SaraJane is earning extra money by giving golf lessons.  The registration fee is $100 and each month is $45.

3. Bellringer Maggie is hiring a caterer for a party she is giving  for her Algebra friends during 4th block. Scrumptious by Fletcher charges $500 to cover expenses  and $55 per hour. A la Ava  only charges $425 for food and expenses and  $70 per hour. Chez Lily charges $62 per hour and an upfront fee of $520. Use Desmos or your graphing calculator to help you determine which company Maggie should hire.

23. GRAPHING INEQUALITIESGameUse 1 (ONE) computer per table.Go to IXL Algebra T.3 to 100% and T.4 to 100%Roll the dice for the x-coordinate and y-coordinateFlip the coin for positive (heads) or negative (tails) signs for coordinates.Graph on paper. First one finished, check on IXL. If correct first 1 place gets 4 pts, 2nd one 3 points, 3rd one 2 points. Last place=0 points. The way you claim your status is turn your paper over and stand up with hands up. Can not be standing and writing. There is a potential for chaos-don’t make us stop the game-be a good sportsman and neighbor.

24. EoS-Evidence of Study Can you… 1.  find the rate of change (slope) given a table, graph, or set of points? 2.  graph a line given in Slope-Intercept, Standard or Point-Slope Form? 3.  Solve for x-intercepts and y-intercepts and interpret what they mean in terms of a context? 4. Convert between the different forms of a linear equation? Slope-intercept, standard, pt-slope 5.  Compare functions (which has greater slope, y-int,)? 6.  Graph a linear INEQUALITY and determine viable solutions?  Unit 3 Test Tuesday be doing Evidence of Study From textbook Extra Practice: Khan Academy IXL
