Answer:
Bus B travel faster
Step-by-step explanation:
The graph of the question in the attached figure
we know that
the linear equation in slope intercept form is equal to

where
m is the slope
b is the y-intercept
x ---> is the time in hours
y ---> is the distance in miles
In this problem we have
Bus A

The slope of the linear equation represent the speed of the bus
so
The speed of bus A is

Bus B
Find the slope
take two points from the graph
(0,0) and (3,200)
The formula to calculate the slope between two points is equal to

substitute


Compare the slope Bus A with the slope Bus B

therefore
Bus B travel faster
There are thirty different express meals possible
Slope=rise/run
goes up 1, to the right 5
rise/run=1/5

x + 3y − y + 3x + 2(2 + 4 + y)
= 4x + 2y+ 12 + 2y
= 4x + 4y + 12
answer
</span>B: 4x+4y+12
