How to translate the image of the linear function y = 2x + 4 from the image of the positive scale function y = 2x?

How to translate the image of the linear function y = 2x + 4 from the image of the positive scale function y = 2x?

The image of the linear function y = 2x + 4
It is obtained by translating the image with positive scale function y = 2x upward by 4 units
