14.23 is your answer!!!!!!!
For this case we have that by definition, the point-slope equation of a line is given by:

We have the following points:

We chose a point:

Substituting in the equation we have:

Finally, the equation is: 
Answer:
OPTION C
The rate for the first is 1 job / 35 minutes and for the second is 1 job / 15 minutes. So combined we get
r = 1/35 + 1/15
3×5×7r = 3 + 7 = 10
r = 10/(105) jobs per minute
We're interested in 1/r
1/r = 105/10 = 10.5 minutes per job
Answer: 10.5 minutes
The answer would be X=1/2y
