Afrequency distribution is a. a graphical device for presenting categorical data. b. a graphical form of representing data. c. a tabular summary of a set of data showing the frequency of items in each of several nonoverlapping classes. d. a tabular summary of a set of data showing the relative frequency.

Option d

Explanation:

Frequency distribution can be defined as a review of every particular value in some factor and the occasions they happen. That is, a frequency distribution  determines the ways frequencies are appropriated over data. Frequency distribution are generally utilized for outlining categorical values or variables.

Thus it is tabular summation or summary of a data set that gives the relative frequency.

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14
