is there a question?

3. anonymous

yes Give an example written in slope intercept form (y = mx + b) of a line parallel to your solution in Part 2.Provide an explanation in a complete sentence of the relationship between the slopes of parallel lines. My solution for the question before this was Y=2x-9 Need to find a line parallel to this solution.

4. anonymous

pick any line with slope 2

5. anonymous

the ":explanation in complete sentences" is that parallel lines have the same slope

6. anonymous

OOOH okay that makes so much sense thank you so much!

7. anonymous

so you can make it $$y=2x$$ or $$y=2x+1$$ or $$y=2x-5$$ or $$y=2x+anything$$

@satellite73 does a perpendicular line have the same Y intercept then?

10. anonymous

not sure what you are asking it is possible that two perpendicular lines have the same y intercept, for example $y=-\frac{1}{2}x+3$ has the same y intercept as $$y=2x+3$$ (they are both 3) but they certainly don't have to have the same y intercept

11. anonymous

maybe if you write the exact question as written i can give a better answer

12. anonymous

Give an example written in slope intercept form (y = mx + b) of a line perpendicular to your solution in Part 2. Provide an explanation in a complete sentence of the relationship between the slopes of perpendicular lines. i have to do the same thing just find a line thats perpendicular to Y=2x-9

13. anonymous

ok forget the y intercept, it has nothing to do with it

14. anonymous

the slope of $$y=2x-9$$ is $$2$$ right?

15. anonymous

yes

16. anonymous

the slope of the perpendicular line will be the "negative reciprocal" of 2, which means flip it and change the sign

17. anonymous

so the slope of the perpendicular line will be $$-\frac{1}{2}$$

18. anonymous

Okay got it i was writing that down as soon as you said flip the sign. All of this is coming back to me now.

19. anonymous

so you can write ANY line with slope $$-\frac{1}{2}$$ you choose

20. anonymous

you good from there?

21. anonymous

yes thank you
