1. y = 5x - 4 is already in y = mx + b format. Solution is y = 5x - 4
2. y = -2x + 3 is already in y = mx + b format. Solution is y = -2x + 3
3. y = 3x + 1 is already in y = mx + b format. Solution is y = 3x + 1
4. 2y = 6x + 2
Divide by 2: y = 3x + 1
Solution is y = 3x + 1
5. y - 5x = 2
Add 5x to both sides: y = 5x + 2
Solution is y = 5x + 2
6. y - 4x + 1 = 0
Add 4x to both sides: y = 4x - 1
Solution is y = 4x - 1
7. y = 5x is already in y = mx + b format. Solution is y = 5x
