Answer:
7.7
Step-by-step explanation:
we basically follow the BEDMAS rule
1st we workout the bracket (7-2)=5
2nd the exponent 3^2=9
3rd the multiplication (7-2) . 4 = 5 . 4 = 20
4th addition 9+20=29
5th step is subtraction 29-6=23
the final step is dividing 23 by 3, which will become 7.7
M=1-5/2-3=-4/-1=4
M=4
(3,5)
5=2(3)+b
5=6+b
b=-1
