The graph suggests that the two lines meet at
If this is true, that point must belong to both lines.
To check this, plug in both equations, and you must get
once you simplifiy all the numbers.
In the first equation we have
In the second,

If for the slower printer it takes 10 hours for the whole thing, how much has it done in 1 hour? well, since it takes 10 hours total, in 1 hour it has only done 1/10 th of the whole work.
the faster printer however, can do it in 6 total, how much has it done in 1 hour? well, 1/6 of the whole work.
now, let's say, they both work together, and it takes "t" hours to finish the whole thing with both rolling.
let's add both rates to see how much that is,
which is 3 hours and 45 minutes.
