Given the points A (8, 5), B (6, 1), C (-3, -1), D (-5, -5), line AB and line CD are _____.

• Parallel

• Perpendicular

• Neither / Intersecting

What is the point-slope form of equation of the line that is PARALLEL to y = -2x - 6 and passes through the point (-3, 11)?

• y - 11 = -2 (x + 3)

• y - 11 = -2 (x - 3)

• y - 3 = -2 (x - 11)

• y + 3 = -2 (x - 11)

Given that y - 11 = (1/2)(x + 3) is the point-slope form of equation of the line that passes through the point (-3, 11) is PERPENDICULAR to y = -2x - 6, what is the slope-intercept form?

• y = (1/2)x + 25/2

• y = (1/2)x + 19/2

• y = (1/2)x + 8

• y = (1/2)x + 7

What is the equation of the line that is PARALLEL and what is the equation of the line that is PERPENDICULAR to y = (1/3)x + 2 and passes through (5, 1)?

• PARALLEL: y = (1/3)x - (8/3)

  PERPENDICULAR y = -3x + 14

• PARALLEL: y = (1/3)x - (2/3)

  PERPENDICULAR y = -3x + 16

• PARALLEL: y = (1/3)x - (1/3)

  PERPENDICULAR y = -3x + 6

• PARALLEL: y = (1/3)x - (4/3)

  PERPENDICULAR y = -3x + 4

• PARALLEL: y = (1/3)x - (7/3)

  PERPENDICULAR y = -3x + 10

The equations y = x and y = -x are _____.

• Parallel

• Perpendicular

• Neither / Intersecting
