Graphing vs. Algebraical solutions

Graphing vs. Algebraical solutions

By Angela Miller

When given two equations we can graph them and where the two lines intersect is your coordinate solution.

In this case (3,2)​

​

​Graphing is one method.

​

One Solution​

When the slope's are the same the lines will be parallel. Since they will never cross there is no solution.

Graphing is one method.

No Solution

​

When the two lines graph one on top of the other they have infinite solutions.

​

Graphing is one method.

​Infinite Solutions​
