PART B: Which phrase from the text best supports the answer to the part A?

6/9 i need more characters in my answer

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.

False  the vector difference between first two points is (3,,3)=(2,2)  the vector difference between second two points is (4,,5)=(1,2)  vectors (2,2) and (1,2) are not parallel so:   false
