Answer: negative.


Step-by-step explanation:

We know that the slope of the line \frac{\text{change in y}}{\text{change in x}}

Therefore, the slope for the given data=\frac{y_2-y_1}{x_2-x_1}

\Rightarrow\ Slope=\frac{795-875}{20-10}\\=\frac{-80}{10}\\=-8...,\text{which is negative.}

Hence, the word which describes the slope of the line representing the data in the table = negative.

Slope = (y2 - y1) / (x2 - x1)
(10,875)(20,795)
slope = (795 - 875) / (20 - 10) = -80/10 = -8....negative slope

Graph the data in the table below. Which kind of function best models the data? write an equation to model the data.
harina [27]

Answer:

A quadratic function.

y=2.5x^{2}

Step-by-step explanation:

If you plot the points given in the table, you obtain the graph shown in the figure attached.

As you can see, it is a parabola, therefore, the function that best models the data is a quadratic function.

By definition, the parent function of a quadratic function is:

y=x^{2}

You can compress or stretch it in the y-direction by multiplying the function by a constant C:

 y=Cx^{2}

If 0, then the function is compressed.

If C>1, then the function is stretched.

You can find the constant of the function asked as following:

- Substitute x=1 into the parent function to obtain the y-coordinate:

y=(1)^{2}=1

Then the point is (1,1)

- As you can see, with x=1 you obtain y=1 in the parent function, and in the function given in the table when x=1, y=2.5, therefore, the function is multiplied by 2.5. Therefore the constant is:

C=2.5

Then the function is:

y=2.5x^{2}
