X Activity 1 Transformer (Part 1) Rewrite the following equations in the form Ax + By = C. Example: y = x - 3 1. y = -x + 4 3(y) = 3x - 3) 2. y = -2x + 6 3y = x - 9) 3. y = 5x + 7 3y = 2x -9 4. y = 3x - 8 -1(-2x + 3y = -9) 2x - 3y = 9 5. y =*

Activity 2 Transformer (Part 2) Rewrite the following equations in the form y = mx + b. Example: 5x - 7y = 2 1. 2x + y = 9 5x - 7y = 2 2. x + 2y = 4 -y = 5x + 2 3. 3x - y = 2 X -5 2 Ex = 5 x + 2 - 3 y = x - ; -> 7 2 у 4. 5x + 2y = 7 5. -3x + 3y - 1 = 0 7​
