A. You divide 1 (infront of x) by 12 to get 12. You divide -6 by 12 to get -2 for the y intercept.
Basically what you have to do is substitute the variables for the values
-4+-9+5= -8
-2-3= -5
2= 2
6-4+1= 3
-9(-2+-4--3)= 27
100 yards minus 41 3/4 which is 58 1/4 divided by 2 which is 29 1/2
The square root of -4 is the same thing as the square root of -1 times the square root of 4. The square root of 4 is 2, but the square root is an imaginary number, i. Since it is an imaginary number, it is indeterminate whether it is a rational or irrational (given current number theory) so the square root of negative 4 is neither rational nor irrational. It is imaginary.
