Answer:
12
Step-by-step explanation:
The mode is the one you see the most.
I prefer to use a midpoint formula that deals with both coordinates at once. For points A and B, their midpoint (M) is
... M = (A + B)/2
We can solve this for B by multiplying by 2 and subtracing A.
... 2M = A + B
... 2M - A = B
For your midpoint M(0, -10) and your endpoint A(-4, -5), the other endpoint will be
... B = 2(0, -10) - (-4, -5) = (2·0 -(-4), 2·(-10) -(-5))
... = (4, -15)

Answer:
y = x + 15
Step-by-step explanation:
You swim 15 minutes more than a friend.The friend swims x minutes.
The amount of time you swim is 15 more than x.
Your time is y
Therefore y = x + 15 would be the equation.
1. -8x = 3x
-11x = 0
x= 0
y= 3(0)= 0
(0, 0)
2. -7x = -4x - 12
-3x = -12
x = 4
y = -7(4)= -28
(4, -28)
