Answer:
the answer is C because the slope of the line is what you need to look for with these kinds of problems. it could be any point on the line, but answer C is the only one of its kind.
Step-by-step explanation:
Note that x and y are nonzero integers. It means that x and y will always have same sign (both are either positive or negative, since they are nonzero). Hence, xy term is always positive.
What problem do you want to ask?
Answer:
If XY = -1 then Y = -1 / X
Substitute the given values of X into the above formula and solve for Y:
X = 1 ⇒ Y = -1
X = -1 ⇒ Y = 1
X = 1/2 ⇒ Y = -2
X = -1/2 ⇒ Y = 2
X = 1/3 ⇒ Y = -3
X = -1/3 ⇒ Y = 3
Additional points:
X = 2 ⇒ Y = -1/2
X = -2 ⇒ Y = 1/2
If X = 0 then Y = 1/0 which means the function is undefined, therefore the curve will get close to Y = 0 (y-axis) but will not touch it.
If Y = 0 then 0 = -1/X which is impossible, therefore the curve will get close to X = 0 (x-axis) but will not touch it.

Step-by-step explanation:
<u>Average Value
</u>
The mean or average of a number n of measurements is defined as the sum of all values divided by n.
The running times in seconds are being improved by the following numbers:
5, 3, 4
This is the dataset where we have to find the mean value. Here n=3. Applying the formula:
