AnnouncementsLast 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.

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

Parallel Lines...NEVER intersect.

Have the same slope.

Have a different y-intercept.

Example: y = ½ x + 1 and y = ½ x - 2

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.

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.

Are the graphs of 4y = -5x + 12 and y = ⅘ x - 8 parallel, perpendicular, or neither?

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?

What is the equation of the line that passes through (2,4) and is perpendicular to the graph of y = ⅓ x - 1

Lines and Transformations1) Main Street is represented by y=2x-4

Lines and Transformations1) Main Street is represented by y=2x-42) If you rotate Main Street 90 degrees counter clockwise about the origin, you

will find 3rd Street.
