Question

The distance d traveled by a car based on time, t, in seconds is given by the function of d = 3t + 1.

Can you please Identify the independent variable, dependent variable, rate of change, and initial value for each situation.

Answer 1

form is

y = m x + b
d = 3 t + 1

m = slope = 3 = rate of change
t is independent
d, the distance depends on t
when t = 0, the initial value of d = 3*0 + 1 = 0+1 = 1
