The temperature dropped 5.8 degrees an hour.
1.05 is the answer to this question.
Answer:
the first one
Step-by-step explanation:
If we have a line, and the endpoints are(x₁,y₁) and (x₂,y₂), the midpoint will be:( (x₁+x₂)/2 , (y₁+y₂)/2 );
Data:
Endpoint₁: (2,-3)
Midpoint: (6,6)
Therefore:
(2+x₂)/2=6
2+x₂=12
x₂=12-2
x₂=10
(-3+y₂)/2=6
-3+y₂=12
y₂=12+3
y₂=15
Answer; the other endpoint of a line will be (10,15)
