Solve by graphing
solve by graphing:
x - 2y = 3
y = 2x - 3
How do I solve this problem? I tried using 0 for y and then 0 for x solved both then chose a third point as 1 giving me the answer x y
0 11 /2
when i tried to graph these 3 points it was not a straight line. any idea what I am doing wrong?
Sorry, am not understanding as of yet......
Thank you for getting back to me, Jeff. I do understand now that I must first treat them as two seperate problems. So, correct me if I am wrong. My delimma is not understanding how to solve. As I said earlier my first attempt to solve I first let y be zero and then solve, then let x be zero and solve, then picked another number for my third point (usually, use 1) and solved. Am I wrong for attempting to solve the problem using a incorrect method? again here is my problem:
solve the system using the graphing method:
x - 2y = -3
y= 2x + 1
again you help is appreciated more than you know! I am 44 and have gone back to college, in my junior year and must pass this class. I have been out of school since 1985!!!!!!!!!!
!I think I solved the above , I treated them as two different problems first let y be o, then x be zero, and used 1 as my last number. I now have two straight lines but they are parallel, meaning there is no solution!!!! I am pretty sure its correct!
