It will quarter the result. (I think so)
Amber could have used cross multiplication.
Have a great day!!!!
Answer:
The distance between the two points is 
Step-by-step explanation:
In order to find the distance between two coordinate pairs, we can use the distance formula:

Our coordinate pairs need to be labeled accordingly, so we can use this naming system:

This assigns a name to our points:
Therefore, we can plug these into the formula and solve:

Therefore, the distance between the two points is
.
You put them in fractions then cross multiple.
18/12 and 3/x so that's 36 equals 18x then you divide 36 by 18 which is 2.
