Use the diagram on the right to answer the following a) Name the circle
b) Name two segments
c) name a ray
d) name an angle whose vertex is point D

see below

Step-by-step explanation:

A circle is named by the point in the center.  

Circle C

A segment  is named by two points on the line.

Segment AD  and segment BC

A ray is a part of a line that has a fixed starting point but no end point.

Ray CE →  Arrow going from C to E

The vertex is in the middle of the angle name that has three letters

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
