Answer:
(0, - 6)
Step-by-step explanation:
Since this is a vertical line then the midpoint of the y- coordinates is
(0 - 12) = - 6
⇒ midpoint = (0, - 6 )
So,
Let's translate this into mathematical form.
x - y = 9
x + 2y = 27
Elimination by Addition
Divide both sides of the second equation by 2
Add the two equations together
Multiply both sides by
Substitute
15 - y = 9
Subtract 15 from both sides
-y = -6
y = 6
Substitute
15 - 6 = 9
9 = 9 This checks.
15 + 2(6) = 27
Distribute
15 + 12 = 27
27 = 27 This also checks.
S = {(15,6)}
