Rule: lines that are parallel have equal gradients.
Therefore y=-4/3x + b.
To find b, you must sub the point (6,2) into the equation y=-4/3x + b.
2= -4/3 x 6 + b
b=-10 (using algebra to solve)
Therefore y=-4/3x - 10.
Driver because it slows them down
Since x is the number of songs he has on his phone and if he adds 20 more, his expression will be: x+20
