Correct answer:
A perpendicular line will have a slope with the opposite reciprocal. In simpler terms, you flip the slope and change the sign, therefore, the opposite reciprocal is 4/10.
Also, are opposite reciprocals parallel or perpendicular?
When lines in a plane are parallel (that is, they never cross), they have the same slope. When lines are perpendicular (that is, they cross at a angle), their slopes are opposite reciprocals of each other.
Likewise, people ask, are the lines parallel perpendicular or neither?
We can determine from their equations whether two lines are parallel by comparing their slopes. If the slopes are the same and the y-intercepts are different, the lines are parallel. If the slopes are different, the lines are not parallel. Unlike parallel lines, perpendicular lines do intersect.
Can 2 lines with negative slopes be perpendicular?
If the slopes of two lines are negative reciprocals, the lines are perpendicular. since their slopes of 0 have undefined reciprocals. Vertical and horizontal lines are perpendicular.
How do you prove opposite reciprocal?
Is and parallel or perpendicular?
What does negative reciprocal mean?
The negative reciprocal of a number is to take negative one, and divide by the value. Simply swap the numerator and denominator and add a negative sign.
What is a opposite reciprocal?
The term opposite reciprocals refers to two numbers that have opposite signs and are flipped fractions of each other. … Second, to be reciprocals, one number should be the flipped fraction, or upside down version, of the other number. For example, the reciprocal or flipped fraction of 3/4 is 4/3.
What is perpendicular opposite?
perpendicular. Antonyms: horizontal. Synonyms: vertical, upright, standing upright.
