when the lines are parallel how are the slopes related? when the lines are perpendicular how are the slopes related?
you have the equation of a line rearrange and determine the slope
I forgot everything about the parallel and perpendicular relations because I learned this in algebra but it wasn't taught in algebra 2 :(
A demonstration would be really appreciated.
you have a second point (rt 3, 1)
for any given line the slope is the same through any 2 points on that line |dw:1440210541130:dw|
Okay thanks for clarifying on the point slope form.
now how would i find the perpendicular and parallel lines?
I know the basics. I know that the slope stays the same but the y intercept is different.
they are negative??
yes. parallel lines have the same slope
no exactly for perpendicular lines the product of the slopes is -1
so back to the question you have the equation of the line in standard form you can rearrange and find the slope Part A parallel lines have the same slope and you have a point on that line find the equation of the parallel line to the one given Part B you can find the slope of the line perpendicular to the one given then using the given point and (x, y) you can find the equation of the line perpendicular to the original one given
now please review the complete post and then answer the question completely
There are infinitely many parallel and perpendicular lines right?
focus on this question
And what do you mean by the product of the slope is -1 for perpendicular lines?
product is what you get when you multiply 2 terms
Ohhh okay this makes more sense about perpendicular lines now, thanks
|dw:1440208587394:dw| Okay so I got the point slope form, but how would i change the equation to make it parallel?
i am not up to date with the problem, but for a line to be paralel the slope must be the same
aslo you would have to isolate the varioble, and simplify
Actually I got it :D YAAAY
YAY :D. congrats :)
