Which line is perpendicular to a line with a slope of [tex]-\frac{5}{6}[/tex]?

A. Line JK
B. Line LM
C. Line NO
D. Line PQ

Answer :

To find the line that is perpendicular to a line with a slope of [tex]\(-\frac{5}{6}\)[/tex], we need to determine the slope of the perpendicular line. Here's how we can do it:

1. Understand Perpendicular Slopes:
- Two lines are perpendicular if the product of their slopes is [tex]\(-1\)[/tex].
- Therefore, the slope of the line perpendicular to a line with slope [tex]\(m\)[/tex] is the negative reciprocal of [tex]\(m\)[/tex].

2. Find the Negative Reciprocal:
- Given the original slope is [tex]\(-\frac{5}{6}\)[/tex], we find the negative reciprocal by flipping the fraction and changing the sign.
- The reciprocal of [tex]\(-\frac{5}{6}\)[/tex] is [tex]\(-\frac{6}{5}\)[/tex].
- The negative reciprocal would then be [tex]\(\frac{6}{5}\)[/tex].

3. Convert Fraction to Decimal:
- Converting [tex]\(\frac{6}{5}\)[/tex] to a decimal gives us [tex]\(1.2\)[/tex].

So, the slope of the line that is perpendicular to the given line with a slope of [tex]\(-\frac{5}{6}\)[/tex] is [tex]\(1.2\)[/tex]. You would look for the line among the options (JK, LM, NO, PQ) that has a slope of [tex]\(1.2\)[/tex] to find the correct answer.
