Question

create a double number line diagram to show the relationship.

1. write a story context that would be represented by the ratio 1:4. complete a table of values for this equation and graph.

Explanation:

Step1: Create double - number line

Draw two parallel number lines. Label the first number line with values based on one quantity and the second with corresponding values based on the other quantity in the 1:4 ratio. For example, if the first line has 0, 1, 2, 3, the second line has 0, 4, 8, 12.

Step2: Write story context

Suppose there are apples and oranges in a basket. For every 1 apple, there are 4 oranges.

Step3: Create table of values

Apples (x)	Oranges (y)
1	4
2	8
3	12

Step4: Graph

On a coordinate plane, with the number of apples on the x - axis and the number of oranges on the y - axis, plot the points (0,0), (1,4), (2,8), (3,12) and draw a straight line through them.

Answer:

Double - number line created, story context: For every 1 apple there are 4 oranges in a basket, table of values shown above, and graph with points (0,0), (1,4), (2,8), (3,12) plotted and a line drawn through them.
