Final answer:

The lines y = 3x + 1 and -3x - 6y = -27 intersect at the point (-7/114, -2/19).

Step-by-step explanation:

To find the point of intersection between the lines y = 3x + 1 and -3x - 6y = -27, we can set the two equations equal to each other:

3x + 1 = -3x - 6y

Now, we can solve for x:

3x + 3x = -1 - 6y

6x = -1 - 6y

6x + 6y = -1

Next, we can substitute the value of x into one of the original equations to solve for y:

y = 3x + 1

y = 3(-1 - 6y) + 1

y = -3 - 18y + 1

19y = -2

y = -2/19

Now, we can substitute the value of y back into the equation 3x + 1 = -3x - 6y to solve for x:

3x + 1 = -3x - 6(-2/19)

3x + 1 = -3x + 12/19

6x = 12/19 - 1

6x = -7/19

x = -7/114

Therefore, the lines y = 3x + 1 and -3x - 6y = -27 intersect at the point (-7/114, -2/19).
