PLEASE I NEED HELP !! question: Find the values of k and b if it is known that the graph of y=kx+b goes through points (2, 10) and (−7, −10).
what is k and what is b
PLEAS

k = 20/9

b = 50/9

Step-by-step explanation:

slope intercept form: y = mx + b

given equation: y = kx + b

(-10-10)/(-7-2)

= 20/9

10= 2 x 20/9 + b

90 = 40 + b

b = 50

y = 20x/9 + 50

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)
