Bar graphs and picture graphs are alike in that they both are graphical representations used to visually present data. The sizes of the bars/pictures in both graphs correspond to the size or frequency of the data represented. They provide a concrete, visual way to compare different sets of data.
A bar graph and a picture graph are alike in that they both are graphical representations of data. These types of graphs are used to visually present quantitative data that can be compared with each other. In both graphs, the length or height of the bars or pictures corresponds to the amount or frequency of the data they represent.
For example, let's say we have data on the number of apples, oranges, and bananas sold in a store. In a bar graph, this data would be represented by bars of different heights, with each bar standing for a different fruit. In a picture graph (or pictograph), the same data would be shown using pictures of apples, oranges, and bananas, with the number of pictures representing the quantity sold.

A. 62.5 Points
B.77.5 Points
C. 82.5 Points
D.93.5 Points
Answer:
The approximate score is:
Option: A
A. 62.5 points.
Step-by-step explanation:
Clearly from the graph we could observe that the line of best fit passes through (0,10) and (4.5,45).
Now we find the equation of line of best fit with the help of formula that is used to find the equation of a line passing through (a,b) and (c,d) as:
Here we have:
(a.,b)=(0,10) and (c,d)=(4.5,45)
Hence, the line of best fit is given as:
Now we are asked to find the math score if she does math homework for 7 hours a week i.e. we have to find the value of y when x=7.
Hence, we put x=7 in the equation to obtain y as:
Hence, the approximate score is:
Option: A
A. 62.5 points.
Answer:
y=-9
