8. graph of an equation – graph of al points with coordinates that are solutions of the equation. linear equation – an equation were the graph of its solution lies on a line.

10. 24 = -12 + 12 24 = 0 no 24 = 12 + 12 24 = 24 yes -12 = 0 + 12 -12 =12 no 0 = -12 + 12 0 = 0 yes

14.  transformation – change in the position, shape, or size of a figure  3 types are slides, flips, and turns  translation – is a transformation that slides. Each point of figure is moved same direction and distance  When new figure is created its called an image. Prime notation is the way to name it.
