Move the line y = - 3x + 1 downward by 4 units and then to the right by 3 units | Math enthusiast | Mathematical art

Move the line y = - 3x + 1 downward by 4 units and then to the right by 3 units

y=-3(x-3)+1-4;
The results are: y = - 3x + 6;

Given that the line y = 3x-3 moves 4 units to the left, the analytical expression of the line is () with y = KX + B

① A function move: up and down (add and subtract in the whole formula), left and right (add and subtract in x), then the topic is y = 3 (x + 4) - 3. Simplify: y = 3x + 9. ② if you move down 6 units, it is: y = KX + B - 6. Think about it carefully, left or right does not mean that every point on the function line moves left or right
