1 Welcome to Math! Put last night s homework on your desk and begin your warm-up (the other worksheet that you chose to save for today)
2 Unit Map - Geometry Thursday - Parallel Lines Cut by a Transversal Friday - Proving Lines Parallel and Perpendicular Monday - Pythagorean Theorem and its Converse Tuesday - Math I Field Test / Work on Test Corrections Wednesday - Distance and Midpoint Formula Thursday - Use coordinates to solve geometric problems Friday - Geometry Review Monday - Geometry Test - 15 school days to review for the EOC
3 Announcements Last unit! Geometry! Math I Field Test is on May 1st (Tuesday!) Geometry test is be Monday after next. EOC review will begin soon - remember your EOC is 20% of your final math grade. The EOC will be on May 30th.
4 On Tuesday May 1st, you will take the Math I Field Test This is a field test - you will not receive a score, nor will I It is used to make decisions about testing for next school year It is shorter than the real Math I EOC, but similar in style - good practice for us You will take it during 1st block, so when you come to school that day you will: Go to the bathroom Put everything in your locker except your calculator, pencil, water, and a book to read Report to your assigned testing location Block 1 - Ms. Haywood s Room - Room 315 Block 3 - Ms. Eisner s Room - Room 316 Block 4 - Ms. Kiker s Room - Room 317
5 Parallel Lines... NEVER intersect. Have the same slope. Have a different y-intercept. Example: y = ½ x + 1 and y = ½ x - 2
6 Perpendicular Lines... Intersect to form a right angle. The slopes are opposite reciprocals. The y-intercepts do not matter. Example: y = ½ x + 4 and y = -2x + 9.
7 Intersecting Lines... If lines intersect but do not form a right angle, they are neither parallel nor perpendicular. Slopes are not equal and not opposite reciprocals.
8 Are the graphs of 4y = -5x + 12 and y = ⅘ x - 8 parallel, perpendicular, or neither?
9 A line passes through (12, 5) and is parallel to the graph of y = ⅔ x - 1. What equation represents the line in slope-intercept form?
10 What is the equation of the line that passes through (2,4) and is perpendicular to the graph of y = ⅓ x - 1
