Today we had a review packet which contained all that we learned. What I learned was that to set up a pair of linear equations you need to figure out what we need to find and then add in the variable meaning in the 2nd equation. I also learned that to test if you need to shade above or below you can test a point by using 0 into the equation and if its true you shade where (o,o) is, if not then shade where (0,0) isn't there.
During class we just review what we learned. I learned that when we substitute a variable we plug the equation into the other to solve it. I also learned that if a number is repeated in the domain then the set of data is not a function since each domain can only have one range. although some were hard I made it through and now I learned I need to review over my notes.
