9 = 90 (means 10 has been multiplied by 9)
8 = 72 ( means 9 has been multiplied with 8)
7 = 56 ( means 8 has been multiplied with 7)
6 = 42 ( means 7 has been multiplied with 6)
Then
3 = 12 ( means 4 has been multiplied with 3)
I hope that from the above deductions you have come to know the relation. I hope the answer has come to your help.
Step-by-step explanation:
1. m = (9-3)/(2-1) = 6/1 = 6 => B
2. m = (-7-5)/(2+1) = -12/3 = -4 => G
3. the horizontal line passes (0,4) => m = 0 =>I
4. m = (2-1)/(8-8) = 1/0 = oo => undefined => A
The answer would be the square root of 25 times 9 im pretty sure its been while and it would be 25*9=225 square root of 225 is 15
