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.

 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.

(x+3, y+1)(x-4, y+5)(x-1, y-9) (X,Y) →(x-1, y-3)(X,Y) →(x+1, y+2) (X,Y) →(x-3, y+2)

 a figure has line symmetry if a line of symmetry can be drawn through the figure so one side is mirror image of the other.

nonone

 Reflection – transformation that flips figure over a line called a line of a reflection
