To know that a relation is a function is it the graph gets approved by the “vertical line text”. If the imaginary vertical lines you draw onto the graph only touch one part of the line, then it is a function. If they touch two or more parts of the line, then the relation isn’t a function.

(Since I cant see the following I’ll also give another tip) If the ordered pairs are given, then if a number in the x points is repeated, then it is not a function. But if I’m y is repeated, it doesn’t matter, it’s still a function. The only thing you need to focus on is on the x list, if one number is repeated then it is not a function.

Answer from: Quest

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.

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.
