A train leaves the station at time t = 0. Traveling at a constant speed, the train travels 220 kilometers in 2 hours. Answer parts a and b.
a. Write a function that relates the distance traveled d to the time t.
The function that relates the distance traveled d to the time t is __
(Type an equation.)
b. Graph the function and tell whether it is a linear function or a nonlinear function. Choose the correct
graph below.

i think the answer is d im not sure

none.

b=-6

compare the slopes

,

m

2

=

0

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
