The statement "It will take her 3 hours to read 120 pages" is the correct option (B) is correct.
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
The complete question is:
Kyoko is reading a book by her favorite author. She read the first 20 pages in One-half of an hour. Reading at the same pace, Kyoko wants to determine if she’ll have enough time to finish the book before she has to go to bed. Reading Time On a coordinate plane, a graph titled Reading Time has a number of hours on the x-axis and the number of pages on the y-axis. A straight line goes through (0, 0), (0.5, 20), and (2, 80). According to the graph, which statement must be true? It will take her 2 hours to read 60 pages. It will take her 3 hours to read 120 pages. It will take her 4 hours to read 180 pages. It will take her 5 hours to read 210 pages.
We have:
Kyoko is reading a book by her favorite author. She read the first 20 pages in 1/2 of an hour.
From the data provided we can frame a linear function:
y(x) = 40x
Plug x = 3
y(3) = 40(3) = 120 pages
Thus, the statement "It will take her 3 hours to read 120 pages" is the correct option (B) is correct.
