Answers for 1.2.1 how can I describe a graph
IrinaVladis [17]
I don't know if this is quite what you're looking for but I think it is a diagram showing the relation between variable quantities, typically of two variables, each measured along one of a pair of axes at right angles.
Hope this helps!

Booker owns 85 video games he has three shelves to put the games on each shelf can hold 40 video games. How many video games doe
sweet-ann [11.9K]

Each shelf can hold 40 video games and Booker has 3 shelves. The question asks how many video games does he have room for, so you can cancel out 85.

An equation would be 40 times 3.

Therefore, Booker has room for 1200 video games.
