pc5
Choose:
 
y = -x - 3
y = x - 3
 
y = -x + 9
y = x + 9



6.
Which equation represents a line parallel to the x-axis?
pc6

Choose:
 
x = -3
 
x = -3y
 
y = 12
 
y = 3x + 2



7.
Which equation represents a line that is parallel to the line whose equation is 2x + 3y = 12?
pc7
Choose:
 
4x - 6y = 2
 
-4x + 6y = 2
 
6x + 4y = -2
 
4x + 6y = 2



8.
Which of the following lines are parallel to
y = -3x + 1?
(Check all that apply, and hit SUBMIT!)
pc8
 
5x - 3y = 2

y = -3x - 1

y - 4 = -3(x + 6)

3x + y = 4

y - 3x = 6

y + 8 = 3(x - 1)

6x + 2y = 10

        



9.
The graphs of the equations y = 2x - 7 and
y - kx = 7 are parallel when k equals:
pc9
Choose:
 
-2
2
-7
7



10.
Which of the following lines are perpendicular to 2y = 4x + 5?
(Check all that apply, and hit SUBMIT!)
pc10
 

y + 1 = -½(x + 5)

y = 2x + 1

y - 3 = 2(x - 4)

2y = -x

y = -2x + 3

y = -½ x - 4

2x + y = 7
