Answer:
linear
Step-by-step explanation:
The line is straight, it's not like going in any other direction at all or anything
Answer:

Step-by-step explanation:
The standard equation of a straight line is of the form:

We have to convert the given equation into above form.
Simplifying the given equation:


.- This is in standard form
where 
(2/3)- students working on math
6-total students
(2/3) of 6 students+= (2/3)x6 = (12/3) = 4
For this case we must indicate which of the equations shown can be solved using the quadratic formula.
By definition, the quadratic formula is applied to equations of the second degree, of the form:

Option A:

Rewriting we have:

This equation can be solved using the quadratic formula
Option B:

Rewriting we have:

It can not be solved with the quadratic formula.
Option C:

Rewriting we have:

This equation can be solved using the quadratic formula
Option D:

Rewriting we have:

It can not be solved with the quadratic formula.
