Note from the author:
A complete formative lesson with embedded slideshow, mini lecture screencasts, checks for understanding, practice items, mixed review, and reflection. I create these assignments to supplement each lesson of Pearson's Common Core Edition Algebra 1, Algebra 2, and Geometry courses. See also mathquest.net and twitter.com/mathquestEDU.

Question 1
1.

Solve It! A contractor needs to build two straight roads, each passing through point A. One road must be parallel to Pine Street, and the other road must be perpendicular to Pine Street. Find the coordinates of a second point the parallel road will pass through and the coordinates of a third point the perpendicular road will pass through. Classify the coordinates below appropriately.

  • (10, 70)
  • (50, 40)
  • (60, 60)
  • On the parallel road
  • On the perpendicular road
  • On neither the parallel nor perpendicular road
