Answer:
point B is (0,1)
Step-by-step explanation: A and the midpoint are 4 units away right so count out B and you get (0,1)
Answer:
Yes, this is proportional, if that's what your asking.
Step-by-step explanation:
Answer:
D [-7, 6)
-7 
x < 6
R [-11, 11)
-11 y < 11
Step-by-step explanation:
Answer:
(2,1)
Step-by-step explanation:
3x+y = 7
-2x +y = -3
Solve the second equation for y by adding 2x to each side
-2x+2x +y = -3+2x
y = -3 +2x
Substitute into the first equation
3x+ (-3+2x) = 7
Combine like terms
5x -3 = 7
Add 3 to each side
5x-3+3 = 7+3
5x = 10
Divide by 5
5x/5 = 10/5
x=2
Now we need to solve for y
y = -3 +2x
y = -3 +2(2)
y = -3+4
y =1
