A point represents a location. A coordinate on a plane .
The intersection of two planes is a line.
Answer:
A) 1/9, 3, 27
Step-by-step explanation:
i think you mean 3^x (and not 3x).
because otherwise none of the answer options withdraw makes any sense.
3^-2 = 1/(3²) = 1/9
3¹ = 3
3³ = 27
If your looking for Standard Form Rewrite it as... 
Abcissa is x, and ordinate is y.
In this case the x is positive, and the y is negative.
Therefore, the answer is "positive, negative"
In this case all you do is add all the numbers, answer is 100
