Answer:
1. −2.1−(5.9+3.7)
2. −20+(−40)+(−60)
3. associative properties
4. commutative properties
5. -43
Step-by-step explanation:
a negative times a negative = a positive
so (a * b) + c = 12
(-2 * -3) +6 = 12
6+6 = 12
To find slope use the formula M = y2 - y1
-----------
x2 - y1
say you were given this (2,3) (-4,5) 2 would be x1 and 3 would be y1, -4 would be x2 and 5 would be y2 then just put it into the formula 5 - 3
--------
-4 - 2
which would be 2/ -6 which would simplify to 1/3
1. (-1,-1) (2,-2)
2. (-3,0) (2,0)
3. (-4,-3) (-1,2)
