# Comparing Equations of Lines

1.For the pairs of lines defined by the following equations indicate with an "I" if they are identical, a "P" if they are distinct but parallel, an "N" (for "normal") if they are perpendicular, and a "G" (for "general") if they are neither parallel nor perpendicular.

3x + 4y + 5 = 0 and y = - 3

4 x - 54 .

x = 2 and y = p.

y = x + 1 and 3x + 5y + 7 = 0.

y = - 3

4 x and 3x + 4y + 7 = 0.

2. For the pairs of lines defined by the following equations indicate with an "I" if they are identical, a "P" if they are distinct but parallel, an "N" (for "normal") if they are perpendicular, and a "G" (for "general") if they are neither parallel nor perpendicular.

3x + 4y + 5 = 0 and 6x + 8y + 10 = 0.

3x + 4y + 5 = 0 and 3x + 4y + 7 = 0.

3x + 4y + 5 = 0 and 3x + 5y + 7 = 0.

-4x + 3y + 5 = 0 and 3x + 4y + 7 = 0.

3. For the lines defined by the following equations indicate with a "V" if they are vertical, an "H" if they are horizontal, and an "S" (for slanted) if they are neither vertical nor horizontal.

3x + 4y + 5 = 0

4y + 5 = 0

3x + 5 = 0

x = 1

y = 1

y = x
