Parallel and Perpendicular Going Through a Point

Determine the equation of a line perpendicular to y=-3x-2 and going through the point (9, 2), in slope-intercept form.

• y=3x+7

• y=-3x-7

• y=3x-17

• y=-3x+17

• y=3x-7

Write in the equation of the line parallel to y=5x+3 and going through (1, 6) in point-slope form. [Do not include spaces in your answer]

Which of the following lines goes through the point        (-3, 4) and is perpendicular to  y = 3/2x + 6?

• y = 3/2x - 6

• y = 2/3x + 3

• y = -2/3x - 2

• y = -2/3x + 2

Slopes of perpendicular lines are...

• negative reciprocals.

• negatives.

• the same.

• always 7.
