Analytic Geometry Reflection

Yay, summer is on its way!
It's Jennie .. K, well analytic geometry, i thought, was the easiest unit.. but that's b4 the test.. anywho.. i thought the easiest part was solving for the 2 & 3 variable systems, though sometimes i had to look over my work for mistakes. the parts that were kind of confusing for me at first was drawing out the line and knowing where to shade it in, but once i understood how to do that, i had an easier understanding of the rest.
