• Find the value of x. Then find the value of < J.

4x + 35

Quizzes.

• They are graded and will be in IC soon—I have no internet at home.

• Most people did a WONDERFUL job. At least a couple perfect scores in every class. I am impressed with you all!

• If you missed it, you have until Thursday to get it made up.

• FYI: The material will show up again on a Unit 1 & 2 Test.

Unit 2: Coordinate Geometry

• Slope—writing equations for lines• Midpoint—find it or use to find an

endpoint• Distance—how far?• Use coordinate geometry to solve

problems about figures (segments, triangles, quadrilaterals)

Parallel

• Looks like:

• Means:

• Slope:

Write an equation:

Parallel to y=3x + 5 and through the point (-4, 2).

Plug it in, plug it in!

Perpendicular

• Looks like:

• Means:

• Slope:

Write an equation:

Perpendicular to y=3x + 5 and through the point (-6, -1).

Plug it in, plug it in!
