6 0

Y = k * x

When x = 7 then y = - 58 

- 58 = k * 7 Divide both sides with 7 

- 58 / 7 = k 

k = - 58 / 7 

y = k * x 

when x = 6 

y = - 58 * 6 / 7 

x = - 348 / 7
which would be -49.7

2 1/2 feet can be written as 2.5 feet.

Divide the total distance by the distance per second:

15.6 feet / 2.5 feet per second = 6.24 seconds.
