# How do you find the slope of a line parallel to the graph of each equation 3x+4y=12?

Apr 28, 2018

See explanation.

#### Explanation:

The lines are parallel if their slopes are equal, so to calculate slope of a line parallel to a given one you have to calculate the given line's slope.

## $y = - \frac{3}{4} x + 3$

The given line and all lines parallel to it hve a slope $m = - \frac{3}{4}$
