Blog 9: Qualities of a Complete Graph

There are 3 things that you need to have when making a graph.#1 is you have to have a scale, meaning that you have to have an X and Y table. #2 is you have to have arows on your line or else you are saying that your line ends when it really doesn’t. Lastly #3 is you have to have labels meaning that you have to have numbers of your graph, because if you don’t than you won’t know when’re you numbers go.

You can tell of an equation has no solution when the numbers don’t match when you get your answer. Another way you can tell is if your solution doesn’t have an X in the answer. For infinite solution you will know because your answer will equal 0=0.

Infinite solutions:
3x -7+9-2x=x+2
x=x

No solution:
-2m-8+m+1=0
-1m-8+1=0
