Answer:

The system has infinite solutions

Step-by-step explanation:

we have

$y=2x+6$ ----> equation A

$3y=6x+18$ ----> equation B

Multiply by $3$ equation A

$3y=3*(2x+6)$ -----> $3y=6x+18$ -----> equation C

equation C and equation B are the same line

The system of equations is a consistent dependent system

The system has infinite solutions

For this, it is kind of like a triangle and having to find the diagonal. Let's see what the two legs of the triangle would be.
Leg one= 7 units
Leg two= 8 units
8²+7²= c²
64 + 49=113
√113≈10.6
The line is 10.6 units long.
