SOLUTION: I hope that I can describe this well enough. I have a problem with a graph that contains two parallel lines. Line 1 has the equation y=2x+1 and Line 2 contains the point (0,-2).

Question 264733: I hope that I can describe this well enough. I have a problem with a graph that contains two parallel lines. Line 1 has the equation y=2x+1 and Line 2 contains the point (0,-2). The problem is asking me to find point P in Line 2. What I know is that P is (?, 0). I've tried (4,0), but the computer program I'm working with doesn't like that answer. Any help would be greatly appreciated!

Any 2 lines that are parallel have the same slope.
The 1st line, , is in the form
,
where is the slope, so
the slope of both lines must be
given:
Line 2 goes through (0,-2)
I can plug this (x,y) into ,
and I can find

Now I know line 2 is
Now I can find (x,0)

So the point asked for is P(1,0)
