What is the slope of the line that passes through the points -2,5 and 1,4 a. -3 b. -2 c. -1/3 d. 1/3

C. -1/3

Step-by-step explanation:

Slope = (y2-y1)/(x2-x1)

         = (4-5)/(1--2)

         = -1/(1+2)

         =-1/3

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)
