Answer:
b = 4/3
m = -5/3
Step-by-step explanation:
3=-m+b
-2=2m+b
Subtract the second equation from the first
3=-m+b
-( -2=2m+b)
------------------------
3=-m+b
+ 2=-2m-b
------------------------
5= -3m +0b
Divide by -3
5/-3 = -3m/-3
-5/3 = m
Now we can find b
3=-m+b
3 = - (-5/3) +b
3 = 5/3 +b
Subtract 5/3 from each side
3 -5/3 = b
9/3 - 5/3 = b
4/3 =b
