Question

Which of the following lines is perpendicular to the equation given below?

Answer 1

Answer:

C

Step-by-step explanation:

x+2y=8x...............

Answer 2

Answer:

• B. x−2y=6

Step-by-step explanation:

Perpendicular lines have negative reciprocal slopes

The given line is

• y = -2x + 8

Perpendicular line to this must have a slope of

• - 1/(-2) = 1/2

Option A

• 2x - y = 12
• y = 2x - 12
• Slope is 2
• No

Option B

• x - 2y = 6
• 2y = x - 6
• y = 1/2x - 3

• Slope is 1/2
• Yes

Option C

• x + 2y = 8
• 2y = - x + 8
• y = -1/2x + 4
• Slope is -1/2
• No

Option D

• 2x + y = 4
• y = -2x + 4
• Slope is -2
• No
