(06.04 MC) The following scatter plot shows the relationship between the weekly number of
hours of watching television and the weekly number of hours spent gardening:

What is the y-intercept of the line of best fit and what does it represent? (1 point)
1)
11.5 hours; the number
television
hours students garden when they do not watch
O2) 9.65 hours; the number of hours students garden when they do not watch
television
3) 9.65 hours; the number of hours students watch television when they do not
garden
4) 11.5 hours; the number of hours students watch television when they do not
garden

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

ratios represent a pattern or relationship that can be scaled.

equivalent ratios are pairs of ratios that represent the same relationship between quantities, and can be generated by multiplying or dividing both quantities in the ratio by the same factor.

in this lesson, students will use double number lines and ratio reasoning to solve ratio problems. by partitioning double number lines into proportionate intervals, students will build an understanding of equivalent ratio relationships as those that are generated by multiplying or dividing two related quantities by the same number. this lesson will build upon students' prior understanding of multiplicative comparisons, number line reasoning and equivalent fractions (while highlighting the difference between equivalent fractions and equivalent ratios); and will build toward future work in this unit on building ratio tables, and work in future grades in proportionality, scaling, and expressing and graphing linear functions.
