Step-by-step explanation:
The slope of the given line is -3. Since perpendicular lines have slopes that are negative reciprocals of each other, the slope of the line we need to find is 1/3.
Substituting into point slope form, we get:
y + 6 = ⅓(x+6)
Given:
The expression is:
To find:
The difference.
Solution:
We have,
It can be rewritten as:
Taking LCM, we get
Therefore, the value of the difference is .
