3. you cannot simplify √30
-12 Celsius because that would equal 10.4 degrees
(3,-1) just fill it in and the only one that makes sense is the first one
2/5 because 10/10 minus 6/10 equals 4/10 which reduces to 2/5
The answer would be y=x+1
this is the answer because the y-intercept is 1. The line goes by 1/1x. 1/1x is equal to 1x. You can take the 1 out and you will get y=x+1
I hope this helps
