Ashford 4: – Week 3 – Discussion 1

Parallel and Perpendicular

Read the following instructions in order to complete this discussion, and   review the example of how to complete the math required for this assignment:

• Given an equation of a line, find equations for lines        parallel or perpendicular to it going through specified points. Find the        appropriate equations and points from the table below. Simplify your        equations into slope-intercept form.

If your first name starts     with

Write the equation of a line parallel     to the given line but passing through the given point.

Write the equation of a line perpendicular to the given     line but passing through the given point.

A or N

B or O

C or P

D or Q

E or R

F or S

G or T

H or U

I or V

J or W

K or X

L or Y

M or Z

• Discuss the steps necessary to carry out each        activity. Describe briefly what each line looks like in relation to the        original given line.
• Answer these two questions briefly in your own        words:
  • What does it mean for one line to be parallel to         another?
  • What does it mean for one line to be perpendicular         to another?
• Incorporate the following five math vocabulary words        into your discussion. Use bold font to emphasize the words in your        writing (Do not write definitions for the words; use them appropriately        in sentences describing your math work.):
  • Origin
  • Ordered pair
  • X- or y-intercept
  • Slope
  • Reciprocal

Your initial post should be   150-250 words in length. Respond to at least two of your classmates’ posts by   Day 7. Make sure you choose people who don’t have the same equations as you   worked. Do you agree with how they used the vocabulary? Do their equations   seem reasonable given what they started with?
