Write an equation in slope intercept form for the line with slope 3/2 and y intercept -1

Start with the slope-intercept formula.

In this formula, is the slope and is the y-intercept.

Substitute in the slope.

Substitute in the y-intercept.

Adding a negative number is the same as subtracting the absolute value of that same number.

Find the absolute value.

answer: ask

step-by-step explanation:

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)
