Given the function y = [2m + 1] x + M-3, if the image of the function is parallel y = 3x-3, find the value of M

Given the function y = [2m + 1] x + M-3, if the image of the function is parallel y = 3x-3, find the value of M

Parallel means the same slope
That is to say, the derivatives are the same
That is: 2m + 1 = 3, M = 1
