I need to graph a system of equations. I'll write it down below. Sorry in advance if it's hard to understand.

4x - 3y = 5 (first half of the system)

-3y = -4x + 5

-3y/-3 = -4x/-3 + 5/-3

y = 4/3x - 5/3

m=4/3 b=- 5/3

y = 4/3x - 7/3 (second half of the system)

m=4/3 b=- 7/3

Have I done everything right so far? What do I do next?
