A linear function has a degree of 1. Any degree greater than 1, is not a linear function.
The linear functions are:
(1/3)x = y - 3 and
y = (2/3)x.
The power of x is both cases is 1.
Answer:
I think (D)
Step-by-step explanation:
The total distance is given as 18 miles
she traveled at 45 miles per hour for 20 minutes
20 minutes = 20 / 60 = 1/3 of an hour
45 miles per hour x 1/3 of an hour = 15 miles driven
18 total miles - 15 miles driven = 3 miles left
she then drove at 20 miles per hour
20 miles per hour / 60 minutes per hour = 1/3 mile per minute = 1 mile every 3 minutes
3 miles x 3 minutes = 9 minutes to drive the final 3 miles
20 minutes + 9 minutes = 29 total minutes to drive to work
she left at 7:15
7:15 + 20 minutes = 7:35 am she arrived at work
-6y=-3x-4 that is the correct awnser
