Amountain's peak is 880 m above sea level while the valley is 139 m below sea level. what is the elevation drop from the top of thew mountain to the bottom of the valley?

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.

2 over 5 and 4 over 15

don’t know last one sorry
