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.
The outlined content above was added from outside of Formative.

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

Problem 5 Got It? The office manager of a small office ordered 140 packs of printer paper. Based on average daily use, she know that the paper will last about 80 days.

What is the equation of the line in standard form?
4y - 7x = 560
7x + 4y = 560
7x + 80y = 560

Error Analysis: Your friend says the line y = -2x + 3 is perpendicular to the line x + 2y = 8. Do you agree? Explain.
No; After converting the second equation to slope-intercept form, we can see that its slope is -1/2. Since -2 and -1/2 are not opposite reciprocals, the lines are not perpendicular.
Yes; After converting the second equation to slope-intercept form, we can see that its slope is 1/2. Since -2 and 1/2 are opposite reciprocals, the lines are perpendicular.
