Solve by Graphing, describe as consistent and independent, consistent and dependent, or inconsistent.  3x+y=-2 6x-2y=10

Solve by Graphing, describe as consistent and independent, consistent and dependent, or inconsistent.  2x – y = 3 x + 2y = 4

Solve by Graphing, describe as consistent and independent, consistent and dependent, or inconsistent.  x + 2y = 5 3x – 15 = - 6y

Solve by Graphing, describe as consistent and independent, consistent and dependent, or inconsistent.  x = 2 y = 0

Solve by Graphing, describe as consistent and independent, consistent and dependent, or inconsistent.  y = x y = -3x + 4

Solve each system algebraically  8x + 3y = -5 10x + 6y = -13

Solve each system algebraically  5x + 4y = 10 -3x – 5y = 7

Solve each system algebraically  4x – 2y = 5 -2x + y = 1

Solve each system algebraically  4x – 2y = 0 -3x + 9y = 5

Solve each system of inequalities by graphing  x – y < 2 x + 2y > 1

Solve each system of inequalities by graphing  x + y > 4 2x – y > 2

Solve each system of inequalities by graphing

 x<2 x>4

Graph, find the vertices, and the maximum and minimum  y>2 1<x<5 y<x+3 f(x, y) = 3x – 2y

Graph, find the vertices, and the maximum and minimum  y>-2 y>2x – 4 x – 2y > -1 f(x, y) = 4x -y
