What is the equation of the line in slope-intercept form?

y = 2x

Step-by-step explanation:

( 0 , 0 ) ( 10 , 20)

Slope = Change in y ÷ change in x

m= 2; (0,0)

y - y1 =m(x - x1)

y - 0 = 2(x - 0)

    y = 2x

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)
