Explanation / Answer

63) ( 2, -5) and parallel to 3x - 4y = -7

-4y = -3x - 7

y = 3/4 x + 7/4

slope = 3/4

equation of line is

y + 5 = 3/4 ( x - 2)

y + 5 = 3/4 x - 3/2

y = 3/4 x -3/2 - 5

y = 3/4 x -13/2

65) ( -8, -1 ) parallel to -15x + 3y = 9

3y = 15x + 9

y = 5x + 3

slope = 5

y +1 = 5 ( x + 8 )

y = 5x + 39
