Parallel line have the same slope. Since the slope of the line is:
4x = 3y
4/3 = y
4/3, we need to set this up in an equation:
y = 4/3x + b
Now, lets add our point in:
y = 4/3x + b
0 = 4/3(-7) + b
0 = -28/3
28/3 = b
Now we know all our information. Form the equation:
y = 4/3x + 28/3
Hope this helped!
