Answer:
The slope is 2.
Step-by-step explanation:
The given line has equation:
.
This is a linear equation in
.
The slope is the coefficient of the independent variable
.
The coefficient of
in
is 2.
Therefore the slope is 2.
Alternatively,
is of the form
, where
is the slope.
Answer:

Step-by-step explanation:
The equation of a direct variation is generally written as:

Where m is the slope of the equation of the direct variation line.
We want a direct variation equation that contains (6,-2).
We substitute the x=6 and y=-2 to find m.

Divide both sides by 6.


The required equation is

Answer:
No
Step-by-step explanation:
The answer depends on what is meant by the "fourth term". By the binomial theorem, one answer could be

By symmetry, another could be
