# MAT 221 Week 3 Discussion 1 Formulas algebra homework help

• 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.
• Use your assigned number to complete.
•  If your assigned number is: Write the equation of a line parallel to the given line and passing through the given point. Write the equation of a line perpendicular to the given line and passing through the given point.
 15 y = 3x + 3; (-1, -1) y = 3x + 3; (-1, -1)

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 classmatesâ€™ posts by Day 7 in at least a paragraph. Make sure you choose people who donâ€™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?
