y = 3x -2 x 1 2 3
y = 3x -2 x 1 2 3 3x 3 6 9
3x -2 x 1 2 3 3x 3 6 9 Remember -2 is constant -2 -2 -2 -2 -2
y = 3x -2 x 1 2 3 3x 3 6 9 Remember -2 is constant -2 -2 -2 -2 -2 y=3x-2 -2 1 4 7
y = 4x +3 x -1 1 2 3
y = 4x +3 x -1 1 2 3 4x -4 4 8 12
4x +3 x -1 1 2 3 4x -4 3 6 9 Remember +3 is constant +3 +3 +3 +3 +3 +3
y = 4x +3 x -1 1 2 3 4x -4 3 6 9 Remember +3 is constant +3 +3 +3 +3 +3 +3 y=4x+3 -1 3 6 9 12
