Question

Two sixth grade science classes are making salt water solutions. The first class (Class A) is using a ratio of three parts salt to five parts water. The other class (Class B) is using a ratio of two parts salt to four parts water. On the same coordinate plane, graph the function for each class. On your graph, make sure to indicate which line belongs to which class.

Answer 1

The graph in the attached figure

Explanation:

Let

x ----> parts of water

y ----> parts of salt

we know that

Class A

`(y)/(x)=(3)/(5)`

`y=(3)/(5)x`

Class B

`(y)/(x)=(2)/(4)=(1)/(2)`

`y=(1)/(2)x`
