Question

1.4.35 Determine Whether The Pair Of Lines Is Parallel, Perpendicular, Or Neither. Y= 8/11X+1 Y= (-11)/8X+1

Answer 1

Answer: They are perpendicular.

Explanation:

Our task is to answer the following question?

Are the following lines parallel, perpendicular, or neither?

`\sf{y=\cfrac{8}{11}x+1}`
`\sf{y=-\cfrac{11}{8}x+1}`

Main idea:

• Parallel lines have the same slope.
• Perpendicular lines have slopes that are opposite reciprocals of each other.

The lines have slopes that are opposite reciprocals; therefore, they're perpendicular.
