We first rewrite the line y - 3x = – 8 in <span>slope-intercept form as:
y=3x-8.
The form y=mx+n is called the "</span>slope-intercept form" because m tells us the slope and n tells us the y-intercept of the line.
Thus, the slope of the line is 3. We know that if a is the slope of any line perpendicular to our line, then the product of these slopes, 3a, is -1.
This means that the slope a is equal to -1/3. We are also given that the perpendicular line contains (3, 2). Thus, we write the equation:

Answer:
Answer:
No solution
Step-by-step explanation:
We have
For the sum it is not correct to assume
Note that for
it is assumed and in your case
for
In fact, considering a set we have
that satisfy
This means that, by definition
Therefore,
because the sum is empty.
For
we have other problems. Actually, this case is really bad.
Note that has no value. In fact, if we consider for the case
, the cosine function oscillates between
, and therefore it is undefined. Thus, we cannot evaluate
and then
has no solution
