f(t)=3t+4
Which statement best describes the y intercept of the graph of the function?
It is equal to 7 and represents the number of stairs William can climb in 1 second

It is equal to 3 and represents the number of stairs William can climb in 1 second.

It is equal to 4 and represents the number of stairs William had already climbed before he started racing up.

Answer 4

I pretty positive it is the last statement. Time is almost always on the x axis so 3 is the dependent variable that is depending on the time.

Answer 5

ok so 3 is x axis and 4 is y?

Answer 6

time is x axis and 3 is y. tbh I don't know where 4 came from that just doesn't make sense.

Answer 7

ok

Answer 8
