Example Questions
Example Question #31 :Graphing
What is the slope of the line with the equation
In the standard form equation of a line,
In this case the line
Therefore the answer is
Example Question #2 :Graphing Lines
What is the slope of the line that contains the points
To find the slope of a line with two points you must properly plug the points into the slope equation for two points which is
We must then properly assign the points to the equation as
In this case we will make
Plugging the points into the equation yields
Perform the math to arrive at
The answer is
Example Question #2 :Graphing Lines
What is the slope of the line
In the standard form of a line
In this case the line
The answer is
Example Question #4 :Graphing Lines
The equation of a line is

Slope:
y-intercept:
The equation of the line is written in slope-intercept form,
Example Question #33 :Graphing
What is the y-intercept of the line
The y-intercept is the point at which the line intersects the y-axis.
It does this at
We plug
Anything multiplied by
Our coordinates for the y-intercept are
Example Question #3 :Graphing Lines
What is the slope of the line
In the slope-intercept form of a line,
In this case the line
has a slope of
The answer is
Example Question #2 :Graphing Lines
What is the y-intercept of the line
In the slope-intercept form of a line,
It does this at
So we plug
to give us
Anything multiplied by
Our coordinates for the y-intercept are
Example Question #2 :Graphing Lines
What is the slope of a line that is parallel to
Parallel lines have the same slope.
If an equation is in slope-intercept form,
In this case
The slope of our parallel line is
Example Question #9 :Graphing Lines
What is the slope of the line that contains the points,
To find the slope of a line with two points you must properly plug the points into the slope equation for two points which looks like
We must then properly assign the points to the equation as
In this case we will make
Plugging the points into the equation yields
Perform the math to arrive at
The answer is
Example Question #10 :Graphing Lines
What is the slope of the line that contains the points,
To find the slope of a line with two points you must properly plug the points into the slope equation for two points which looks like
We must then properly assign the points to the equation as
In this case we will make
Plugging the points into the equation yields
Perform the math to arrive at
