What is the equation of the following line written in general form? y
(4.5)
(1,2)
.
Oy -x +1 = 0
Ox-y+1=0
O-X-y+1=0

x-y+1 = 0

Step-by-step explanation:

Replace x & y of each coordinates into the function then you'll get the answer.

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
