A transformation that shifts or slides every point of a figureor graph the same distance in the same direction.

A transformation that "flips" a graph or figure across a line such as across the x-axis.

Consist of two or more linear equations that have the same variables.

An ordered pair that satisfies all of the equations in a linear system. The intersection point where the lines cross.

A method used to solve systems of equations in which one variable is elimnated by adding or subtraction two equations of the system and solving for the variable.

A method used to solve systems of equations by solving an equation for one variable and substiutuing the resulting expression into the other euqation(s)

Consists of at least two linear inequalities in the same variables . Given the inequaility, the lines are either dashed or solid and the region iis shaeded above or below the line.

Any ordered pair that satisfies all the inequalities in a linear system. The shaded region in a coordinate plane consisting of ordered pairs whose coordinates are solutions to both inequalities in the system.
