Example Question #1 : How To Find The Slope Of Parallel Lines
What is the slope of a line parallel to the line: -15x + 5y = 30 ?
1/3
30
3
-15
3
First, put the equation in slope-intercept form: y = 3x + 6. From there we can see the slope of this line is 3 and since the slope of any line parallel to another line is the same, the slope will also be 3.
Example Question #11 : Parallel Lines
What is the slope of any line parallel to –6x + 5y = 12?
6
12
12/5
5/6
6/5
6/5
This problem requires an understanding of the makeup of an equation of a line. This problem gives an equation of a line in y = mx + b form, but we will need to algebraically manipulate the equation to determine its slope. Once we have determined the slope of the line given we can determine the slope of any line parallel to it, becasue parallel lines have identical slopes. By dividing both sides of the equation by 5, we are able to obtain an equation for this line that is in a more recognizable y = mx + b form. The equation of the line then becomes y = 6/5x + 12/5, we can see that the slope of this line is 6/5.
Example Question #3 : How To Find The Slope Of Parallel Lines
What is the slope of a line that is parallel to the line 11x + 4y - 2 = 9 – 4x ?
We rearrange the line to express it in slope intercept form.
Any line parallel to this original line will have the same slope.
Example Question #21 : Parallel Lines
In the standard (x, y) coordinate plane, what is the slope of a line parallel to the line with equation 
Parallel lines will have equal slopes. To solve, we simply need to rearrange the given equation into slope-intercept form to find its slope.
The slope of the given line is 
Example Question #1 : How To Find The Slope Of Parallel Lines
What is the slope of a line that is parallel to the line 
Parallel lines have the same slope. The question requires you to find the slope of the given function. The best way to do this is to put the equation in slope-intercept form (y = mx + b) by solving for y.
First subtract 6x on both sides to get 3y = –6x + 12.
Then divide each term by 3 to get y = –2x + 4.
In the form y = mx + b, m represents the slope. So the coefficient of the x term is the slope, and –2 is the correct answer.
