Question

interpret constant of proportionality in graphs
the graph shows the relationship between the length of time ted spends
knitting and the number of scarves he knits.
what does 16 mean in this situation?
choose 1 answer:
ted has to knit 16 scarves.
ted knits 16 centimeters of scarf in an hour.
it takes ted 16 hours to knit a scarf.

Explanation:

In a proportional relationship graph, the point \((x,y)\) represents \(x\) units of the independent variable (scarves) and \(y\) units of the dependent variable (hours). Here, the point \((1,16)\) means when \(x = 1\) (1 scarf), \(y=16\) (16 hours). So it takes Ted 16 hours to knit a scarf.

Answer:

C. It takes Ted 16 hours to knit a scarf.
