4. Is the graph an example of direct variation? If so, what is the constant of variation?

C) yes, 2

Step-by-step explanation:

A direct variation means that the graph is a straight line. In this case it is:

Yes, the graph is an example of direct variation.

To find the constant of variation, you can use the formula:

y =

Now, substitute the x- and y-variables for a given point:

1 =

Finally, solve for k:

1 =

k = 2

The constant of variation is 2.

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "
