Answer:
c=3d
Step-by-step explanation:
What equation models the data in the table if d = number of days and c = cost? Days Cost 2 6 3 9 5 15 6 18
Answer: An equation is a statement used to show the relationship between variables and shows the equality between two expressions. We want to find the relationship between the number of days and the cost.
Given that:
Days Cost
2 6
3 9
5 15
6 18
Lets take the ratio of days to cost using the first row:
The relationship c = 3d is true for all values of days and cost
See attached graph.
The y-intercept is (0, 1), since the line is at that point when it intersects with the y-axis.
The common ratio is 1/4, since the y value multiplies by 1/4 for each unit on the x-axis.
