Train from Washington, D. C. To Chicago stops first in Pittsburgh and then in Cleveland. The distance from Washington, D. C. To Pittsburgh is miles less than twice the distance from Pittsburgh to Cleveland. The distance from Cleveland to Chicago is miles more than the distance between Pittsburgh and Cleveland. If the entire train ride is miles, how far is the train ride from Cleveland to Chicago?

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

answer: the first graph

step-by-step explanation:

answer: do we write it

step-by-step explanation:

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
