The distance, d, measured in miles, that hye drove is d = 45.2t, where t is the time in hours.

what is the constant of proportionality?

enter your answer as a decimal in the box.

45.2  is the constant of proportionality

Step-by-step explanation:

Direct proportionality says that:

then the equation is in the form of:

, where k is the  constant of proportionality

As per the statement:

The distance, d, measured in miles, that Hye drove is

d = 45.2t,         .....[1]

where,

t is the time in hours.

By definition of direct proportionality:

⇒

On comparing with [1] we have;

k = 45.2

Therefore, the constant of proportionality is, 45,2

f(x) = y

f(-3) = -5
