Question

Isabel is pulling water up from an old-fashioned well. She lifts the bucket of water at a rate of 4 ft/s, and after 1 s, the bucket is 1 ft below the top of the well. What is the equation in point-slope form of the line that represents the height of the bucket relative to the top of the well? y [ Select ] [ Select ] = [ Select ] (x - [ Select ] )

Answer 1

y + 1 = 4 (x - 1 )

Answer 2

Point slope form is y+1=4(x-1)

Explanation:

She lifts water at a rate of 4ft/s.

After 1 second, the bucket is 1 feet below the top of the well. So, point form of this would be (1,-1).

Here, let's use the slope m= rate = 4 ft/s

Point as (1,-1)

So, y-(-1)= 4(x-1)

Simplify, it gives

y+1= 4(x-1)
