Answer:
C.)
Step-by-step explanation:
There are multiple technical ways to explain this but the best one that works for me is the "vertical line test" can be used to find a function or non function. All you have to do is position your pencil vertically, place it to the far left of the graph drag it horizontally across to the right side of the graph. If your pencil is making contact with two lines at one time, it is NOT a function. Hopefully this makes sense.

Algebra
Step-by-step explanation:
Answer:
It is required to draw a number line showing equivalent fractions.
'Equivalent fractions' are the fractions having same value even though the digits involved are different'.
For example: Consider, 
and 
.
Now, we have,
= 0.5
= 0.5
Thus, the both fractions have the same value, even though we are dividing different digits.
Thus, and are called equivalent fractions.
So, we plot them on the number line, resulting in the following figure with point P = 0.5.
Multiply 50 by .4 or .40. Both give the same answer, which is 20.
