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

The  point slope equation of a line that is perpendicular  to the line
 y= - 4x + 5  and passes through 
(5, -6)

• y + 5 = 4 ( x - 5)

• y + 6 = 4 (x + 5)

• y + 6 = 1/4( x + 5)

• y + 6 = 1/4(x - 5)

The point slope equation of a line that is perpendicular to the line
y= - 4x + 5 and passes through
(5, -6)

• y + 5 = 4 ( x - 5)

• y + 6 = 4 (x + 5)

• y + 6 = 1/4( x + 5)

• y + 6 = 1/4(x - 5)

• y - 5 = 4 (x - 2)

• y - 5 = - 4 (x - 2)

• y - 5 = 2 (x + 4)

• y - 5 = 2 (x - 4)

• y - 4 = 2 (x - 1)

• y - 1 = 4 (x - 4)

y = -2/3x + 2
y = 3/2x + 9
These lines are ​ (a)   because the slopes are ​ (b)   .

• perpendicular

• opposite reciprocals

• Parallel

• Neither

• the same
