I have these 3 things that I don't really understand how I should approach them. I guess my terminology might be wrong, but try to understand. This is a course of analytic geometry. Any halp is appreciated. I know how to do the calculations, I just don't know what to calculate.

1. Line's distance of point (0,6) is 2. Line goes through origo. What is the line's equation?

2. What are the equations of the lines, that go through point (-1,-2) and which distance from point (2,-1) is 1?

3. Define a point from the line y=2x, that is equally far from the point (-1,3) and line 2x-3y-3=0

1. (0,6) through origin would be a vertical line

2. assuming its only talking about vertical or horizontal distance from point 2,-1, the lines you want are from (-1,-2) to (1,-1) and (-1,-2) to (-2,-3)? solve for slope and use point-slope form, etc

3. donno

doing it yourself is better but i'm pretty sure this can help if you read it: http://www.mathsisfun.com/geometry/index.html

i've never taken any courses in geometry, but this is high school math if i'm clearly mistaken?

Do your X/Y t-chart, plug in 'x' values, solve for 'y', draw shit out on a graphic.

It's very easy when you do that if you are having trouble.

rawr doesn't anyone else prefer to solve a problem without help for sake of the enjoyment gained by solving it?

donno why i need to be mad here, my bad

dear rew

this is the first time i have ever asked for help in the internets regarding homework and i can assure you i have been pondering these questions for a while now

@task line's distance from point (0,6) is 2 so i figured it would go up quite steeply?
thanks everyone, i'll try again later

distance from (0,6) = 2 in what direction?

cause equation of the line that goes through (2,6)(0,0) is different than line that goes through (-2,6)(0,0) or (0,8)(0,0) etc etc

if u saw my work with the fried chicken, you'd distrust my ability to help with anything, ever.

just distance, last class we learned how to determine points distance from a line if you know the line's equation, now i should just know how to sort of reverse it in a clever manner

well, since it doesnt specify a vector or a direction, theres infinitely many different lines that are that distance away, so donno

if you just move in one of the cardinal directions in the xy plane, youve got from the origin to (0,4) (0,8) (2,6) (-2,6), so solve for slope
