The table below does not represent a function why? ​
Sergeu [11.5K]

Answer:

Because X (10) repeats

Step-by-step explanation:

A function has no repeated X but here in your x variable 10 is there twice so therefore it is NOT a function

You can use the pencil test also in a graph, align your pencil vertically and see if there are multiple points that have the same X and if there isn't any repeated its a function.

Points X, Y, and Z are colinear.<br> X<br> What is the slope of YZ in simplest form?
DIA [1.3K]

Based on the calculations, the slope of line YZ in simplest form is equal to 2.

<h3>How to determine the slope of YZ?</h3>

Mathematically, the slope of a straight line can be calculated by using this formula;

Slope, m = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope, m = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}

Since points X, Y, and Z are collinear, we can deduce that the line passes through line Z at 6 units form the origin and 3 units for Y from the origin.

Substituting the parameters into the formula, we have;

Slope, m = \frac{6\;-\;0}{3\;-\;0}

Slope, m = 6/3

Slope, m = 2.
