Example Question #1 : How To Find The Slope Of Parallel Lines
What is the slope of a line parallel to the line described by 3x + 8y =16?
First, you should put the equation in slope intercept form (y = mx + b), where m is the slope.
Isolate the y term
3x + 8y – 3x = 16 – 3x
8y = 16 – 3x
Rearrange terms
8y = –3x +16
Divide both sides by 8
The slope of the line is -3/8. A parallel line will have the same slope, thus -3/8 is the correct answer.
Example Question #2 : How To Find The Slope Of Parallel Lines
What is the slope of a line parallel to 
When two lines are parallel, they have the same slope. With this in mind we take the slope of the first line which is 
If 
Example Question #3 : How To Find The Slope Of Parallel Lines

Parallel lines have identical slopes. To determine the slope of the given line, transform 
Example Question #4 : How To Find The Slope Of Parallel Lines
Which equation described a line parallel to the line that connects points (–8,9) and (3,–4)?
In order for two lines to be parellel, their slopes have to be the same.
Find the slope of the line connecting those two points using the general slope formula, 
Match this slope value with one of the possible choice of equations. The correct equation is 
Example Question #5 : How To Find The Slope Of Parallel Lines
Which of the following are NOT parallel to each other?
Four of the answers are not in slope-intercept form.
For the lines to be parallel, all must share the same slopes.
To identify the slopes, this is the
