parallel lines have equal slopes

anonymous · Answer

It's also worth mentioning that perpendicular lines have slopes that are opposite reciprocals of eachother.

anonymous · Answer

Based on the fact that parallel lines have equal slopes, what answers can we throw out right away?

anonymous · Answer

Use the point given, which is (x1,y1) and plug it into the point-slope formula.

y - y1 = m ( x - x1 ) where m is the slope. 

Solve for y and you have your answer
