The linear model d = 0.15+.35t represents the data found for the dive of a local swim team where t represents the duration of the dive in seconds and d is the depth of the dive in feet. What does the slope represent?

A
That if the dive was increased by 1 second, the depth would increase by about .15 feet.
B
That if the dive was increased by 1 second, the depth would increase by about .35 feet.
C
That if the dive was increased by .15 seconds, the depth would increase by about 1 foot.
D
That if the dive was increased by 35 seconds, the depth would increase by about 1 foot.
