Is xy/y^2 a polynomial

1 answer:

4 0

The expression simplifies to x/y, so the answer is no, it is not a polynomial. The fact that a variable is in the denominator means it's not a polynomial.

Write an ordered pair for each point graphed below.

Viefleur [7K]

Answer:

$\boxed{(-1,4)}$

Step-by-step explanation:

The point is located in Quadrant II of the graph, where x-values are negative and y-values are positive.

Each marking on the graph represents one unit of distance. The two <em>axes</em> meet at the origin, where the coordinate point is equal to $(0,0)$ .

So, you can count backwards once from the origin to get your x-value ⇒ $-1$ and count up upwards four times from $x=-1$ to get your y-value ⇒ $4$ .

Finally, place these in a coordinate point $(x,y)$ ⇒ $\boxed{(-1,4)}$ .
