Describe how to create the graph of the direct-variation relationship "y varies directly with x where y = -8.4 when x = 4."

Using a proportional relationship, the graph of the proportional relationship is sketched at the end of this answer.

"y varies directly with x", hence, the equation is modeled by:

y = -8.4 when x = 4, hence, we can use it to find a.

Hence, the equation is:

The graph is sketched at the end of this answer.

the answer is 18 units because there are 18 small cubes inside the rectangle

hope this and p.s i am also in k12
