Please help The graph shows the progress of a train travelling between cities.

a) How far does the train travel in the 4 hour journey?

b) Write down a unit rate which compares the distance travelled with the time taken.

A) It will take 4 hours to get to a distance of 240.

B) If we find the unit rate of 240 by 4, divide 240 by 4, which is 60.

Step-by-step explanation:

A) Look at the graph, you see the dot is left by 240 and down by 4. So it would take 4 hours to get to a distance of 240.

B) Like I said, we divide 240 by 4. Make sure to put 1 as the denominator, and divide the top and bottom by 4.

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
