What is the intensity (I) in watt/m2 of a sound wave that has a sound level reading of 125 dB, the loudness of an average fire alarm?

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

i believe that the answer is

b. y-1=-2(x-4)

hope this !

are ya tryin to ask something or is this a statement
