8.6 Parallel/Perpendicular Lines
Determine if these pair of lines are parallel (||), perpendicular ( ) or neither.
1.
y – 3 = 6( x + 3)
2.
5x – y = 10
6y = x + 12
y = -⅕ x + 4
3.
3y = 2x + 10
4.
y + 12 = -5 (x – 2)
2x – 3y = 15
5x + y = 4
5.
3x – 4y = 18
6.
2y = 8x – 10
y = -¾x
y – 4 = -¼ (x + 6)
Write a perpendicular line to:
7.
y = -4x + 5 thru (-2, 3) in standard form
8.
y + 3 = ½ (x –9) thru (5,2) in standard form
9.
x = 5 thru (-9, 10)
10.
y= -3 thru (-2, -7)
11.
4x – 2y = 11 thru (4, -1) in slope intercept form
12.
y = 6x – 3 thru (-6, -4) in point-slope form
13.
8x – 2y = 11 thru (9, 1) in point-slope form
