are slopes equal or not ?
OpenStudy (anonymous):
Parallel lines have the same slope, perpendicular lines have a slope that is a negative inverse.
OpenStudy (anonymous):
@gypsy1274 so its perpendicular
OpenStudy (dumbcow):
what is slope of 1st line? 2nd line?
OpenStudy (anonymous):
Solve the second equation for y, then answer @dumbcow's questions above to find the answer to your question.
