Answer:
{(3,-2), (4,-2),(5,-2), (6,-2)} this relation is not a function.
Isolate the variable by dividing each side by factors that don't contain the variable.
Inequality Form:
x
≤−
2
remember that you have to do the same to both sides

minus 16 both sides



mulitply both sides by 4

![(x)(\frac{4]{4})>72](https://tex.z-dn.net/?f=%28x%29%28%5Cfrac%7B4%5D%7B4%7D%29%3E72)


DE~JK the only two side lengths you know, so it is the only possible answer.
