ANSWER: (A) y= 10/3

EXPLANATION:

Create an equation for the graph⇩

From looking at the graph, the lemon juice in ounces is 3 times less than the water in ounces. Using this, we can create the following equation with y standing for the lemon juice and x standing for the water.

Y= x/3

Since we are solving for the amount of water, we have to substitute x for 10⇩

Y= 10/3
