Answer:

a)The equation of the Parallel line to the given line is

                                        7x -y +18 =0

b) The equation of the Perpendicular line to the given line is

                                             -x +7y +18 =0

Step-by-step explanation:

Step(i):-

Given that equation of the line y = 7x -5

                                              7x -y -5=0

The equation of the Parallel line to the given line is

                                             7x -y +k=0

This line is passes through the point ( -3,-3)

                                            7 ( -3) -(-3)+k=0

                                         -21 +3+k=0

                                           -18 +k=0

                                                k =18

The equation of the Parallel line to the given line is

                                        7x -y +18 =0

Step(ii):-

Given that equation of the line y = 7x -5

                                              7x -y -5=0

The equation of the perpendicular line

                                           b x -ay +k=0

The equation of the Perpendicular line to the given line is

                                             -x +7y +k=0

This line is passes through the point ( -3,-3)

                                          -(-3)+7(-3) +k=0

                                         3 - 21 +k=0

                                        -18 +k=0

                                             k =18

The equation of the Perpendicular line to the given line is

                                             -x +7y +18 =0
