You are located at 34 on the number line and your friend is on 53. Where would the point be located if you were to partition your location to be a ratio of 4:1. Where would be point be located, rounded to the nearest hundredths place?

The answer is the first one

The slope best fit isc. 1/6 mile per hour

So the first thing we do is to multiply the top equation by 3. the reason i want to do this is i notice there will be a 6y on both equations and can possibly add/subtract them. so we get 6y = -3x + 27. adding that and the second equation we get 6x = 27-15 which is 12. divide by 6 and we get 2. ∴ x = 2. substituting 2 into the first equation we get 2y = -2 + 9 which is 7. divide by 2 and we get 7/2. ∴ y = 7/2, x = 2.
