Question 462063: Dear Sir or Madame:
I am currently taking an Algebra 2 course and have a help CD; however, even after watching the CD for a certain problem, I still could not figure it out. It concerns graphing two-variable equations. I don't know how or why they gave the answer they did. If you can help, I would really appreciate it. Here are the following two problems they gave me:
Graph each two variable equation below.
14. y = 2x – 5
15. y = -4x + 1
Again, if you can help, I would really appreciate it. Thank you for your time and effort.

You can put this solution on YOUR website!
Graph each two variable equation below.
14. y = 2x – 5
You need 2 points to determine a line.
Let x = 0, then y = -5
Let x = 2, then y = -1
----
Plot (0,-5) and (2,-1) and draw a line thru them to get:

-----------------------------------------------
15. y = -4x + 1
Let x = 0, then y = 1
Let x = 2, then y = -7

Plot (0,1) and (2,-7) and draw a line thru them to get:
