Show that T is a linear transformation by finding a matrix that implements the mapping. Note that x 1, x 2, ... are not vectors but are entries in vectors. Upper T (x 1 comma x 2 comma x 3 )equals(x 1 minus 2 x 2 plus 2 x 3 comma x 2 minus 5 x 3 )

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
