The Solution:
Given the equation of a line:
We are required to find the equation of a line that is perpendicular to the given line and passes through the point (-12,-1).
Step 1:
Determine the slope of 6x-y-4=0.
The coefficient x, after making y the subject of the formula, is the slope of the given line. That is:
Step 2:
Find the slope of the required line:
Since the two lines are perpendicular, the slope is:
Step 3:
Find the equation of the line that passes through point (-12,-1)
By formula,
In this case,
Substituting these values in the formula, we get the required equation is:
Cross multiplying, we get
Therefore, the correct answer is:
Answer:
Given the radical form:
Use the exponent rules:
we can write as:
then;
=
Therefore, in exponential form is
