4. Write the equation of the line that is parallel to y=-3/4x+12 that passes through (-2, 4).

5. Given line
l, y=3/2x+6
and line
m, 3x-2y=18,
which of the following statements best describes the lines?

A) There is no special relationship between the slopes, so lines l and m are intersecting lines.
B) Lines l and m are the same line, or coinciding.
C) Lines l and m are perpendicular, so their slopes are opposite sign reciprocals.
D) Lines l and m have the same slope, so they are parallel.

6. Which of the following statements correctly describes the relationship between the following lines?

line k: y=5x-9

line j: y=5x+9

A) The lines have the same slope, so line k is perpendicular to line j.
B) The lines have the same slope, so line k is parallel to line j.
C) There is no special relationship between the slopes, so line "k is intersecting line j.
D) The lines have the same slope and y-intercept, so line k is coinciding with line j.
