Answer:
Y:
-1
0
2
4
Step-by-step explanation:
if I understand correctly, Y= x+4, you should add all the numbers in the X column by 4
Example:
-7
-7 plus 4 would be -3
the reason for this is when adding negative numbers you always go down instead of going up because if you add the way we add normal number then you will keep going deeper into the negative numbers.

Step-by-step explanation:
Find the distance between the three pairs first using the distance formula:

Take the first two points,
and insert the values:

Simplify parentheses (two negatives makes a positive):

The distance between the first two points is 5. Use the nest two points,
and insert values:

Simplify parentheses:

The distance between the nest two point is about 4.5. Use the remaining two points,
and insert values:

Simplify parentheses (two negatives makes a positive):

The distance between the last points is 5. Add the distances together to find the perimeter of the triangle:

The perimeter is about 14.5.
