Week 3 Discussion 3

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.  Sinplify your equations until slope-intercept form.

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

y=1/2x+3; (4,-1)

Merited the equation of a line perpendicular to the given line and passing through the given point.

y=1/2x+3; (4,-1)

Discuss the steps necessary to carry out each activity. Describe briefly what each line looks like in relation to the origI already given line.

 Answer these two questions briefly in your own word:

What does it mean for one line to be parallel to another?

What does it mean for one line to be perpendicular to another?

IncorporTe the following five math vocabulary words into your discussion. Use them in BOLD font to emphasize words in your writing. (Do not write definitions for the words. Use them appropriately in sentences deac your math work.

Orgin

ordered pair

X- or y- intercept 

slope

reciprocal
