What is the slope of a line parallel to $2x+4y=-17$? Express your answer as a common fraction.
Plan:
- Convert it into the y = mx + b form. m is the slope
- The line that is parrelel to the given line has the same slope.
Converting:
(1.) 2x + 4y = -17
(2.) 4y = -2x - 17
(3.) y = -(1/2)x - 17/4
[Now it's up to you to find the slope.]
