Given 
, which graph is the correct one?
Given
First, solve for 
: 
.
Then, graph the 
at

Since the slope of the line is 
, you can graph the point 
as well.
There is only one graph that fits these requirements.

Which of the following does not lie on the line given by the equation below?
Which of the following does not lie on the line given by the equation below?
To determine if a point lies on a line, plug in the x-value and y-value to see if the equation is satisfied. We can do this for each choice to check.
For example:
: 
Since both sides are equivalent, this point does lie on the line.
We can continue to do this for each of the points until one point does not work out.
Thus, this point does not lie on the line. Thus, this must be the solution.
