Show all work to write the equations of the lines,

Show all work to write the equations of the lines, representing the following conditions, in the form y = mx + b, where m is the slope and b is the y-intercept:

Part A: Passes through (−2, 1) and parallel to 4x − 3y − 7 = 0

Part B: Passes through (−2, 1) and perpendicular to 4x − 3y − 7 = 0
