Mathematics - 16 December 2007

The question is:
Find the equation of the line that is perpendicular to 4x+3y=6 and that passes through the point (-1,-4).

The answer is y=3/4x-13/4, but i don't understand how to get that. Could anyone please explain this to me? Thank you very much!

I am going to ask a series of questions; thank you for the most helpful answers that you can give.( I KNOW THAT EVERYBODY IS DIFFERENT, ASSUME THE PERSON IN THESE SITUATIONS IS NORMAL-AVERAGE)

1. In mathematics do you think that it is intrest in the class that can help a student, or do you think that it is all based on natural ability?

2. Is consitancy in a math class crucial to the studen learnig mathematics?

3. Do you think that a person who is average in math with an intrest to learn and be very good; can become kind of like a genius or very good at it?

4. In all forms of mathematics both advanced and low are there formulas to evey problem?

5. Is math based more on formula, or figuring things out?

Thank you for the most helpful answers that you can give.,

If possible can you also leave the last math class you took, the grade, and your relation to math, thank you.

(tan x + cot x)/sec² x . I keep getting cos² x for the answer, but whenever I plug in an angle, I get two different answers. I multiply both sides by cos²x (inverse of sec²x), and then do a process of elimination with the cosines and sines, and get cos²x. What is the correct answer to this problem?

Can someone explain me how to graph the inverse of a function on a TI-83 plus. example x = y + 2, I know the inverse is y = x - 2. I am using my TI-83 plus, how can I graph the inverse of y = x^2, I know that on my TI-83 on
Y1 = X^2
Y2 = ? I just need to know what to input on Y2, thanks for anyones help

I don't know if I understood what "roots" are correctly.

The problem was to compute the sum of all the roots of
(2x + 3)(x - 4) + (2x+3)(x - 6) = 0

I figured x = -1.5
= 4
= 6

and the answer I got was 8.5

Can someone tell me if I got this problem right? and if it's wrong, why? Thanks!
