# GMAT Math : Calculating the slope of parallel lines

## Example Questions

### Example Question #1 : Calculating The Slope Of Parallel Lines

What is the slope of the line parallel to ?     Explanation:

Parallel lines have the same slope. Therefore, rewrite the equation in slope intercept form :    ### Example Question #2 : Calculating The Slope Of Parallel Lines

Find the slope of any line parallel to the following function.       Explanation:

We need to rearrange this equation to get into form. Begin by adding 6 to both sides to get Next, divide both sides by 4 to get our slope So our slope, m, is equal to 3/4. Therefore, any line with the slope 3/4 will be parallel to the original function.

### Example Question #3 : Calculating The Slope Of Parallel Lines

A given line is defined by the equation . What is the slope of any line parallel to this line?      Explanation:

Any line that is parallel to a line has a slope that is equal to the slope . Given  and therefore any line parallel to the given line must have a slope of .
