2.) Find the equation of the straight line:

d. through (3,-4) and perpendicular to the line y = 2x

e. through (-2, 1) and perpendicular to the line 2x + y + 3 = 0

f. through (7,-2) and perpendicular to the line 3x-y-5=0

g. through (-3,-1) and perpendicular to the line 4x-3y+2=0

h. passing through the origin and parallel to the line x + y + 3 = 0

i. through (3,7) and parallel to the line 5x-y-2=0

j. through (0, -2) and perpendicular to the line x - 2y = 9

k. perpendicular to the line 3x+2y-1 = 0 and passing through the point (-2, 4).
