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
