B. (-5, -2)
4(-5) -5(-2)= 24
-20 +10 = 24
-10 =24
False
C. (0,6)
4(0) -5(6) =24
-30 =24
False

2 negatives can be converted to a plus sign. -(-x) can be +x or just x.
-54--23
-54+23
<u>23-54=-31</u>
78--4
<u>78+4=82</u>
-48/-6
Now let's pause fer a sec. When a negative is being divided by another negative, the quotient(answer to division problem) becomes a positive.
<u>-48/-6=8</u>

<u>50*-4=-200</u>
