Question 471412: Suppose I have a point on a line which is (3,4) and suppose I know the slope of the line is 2.
I want to find a two points on the line with one point on one side of (3,4) and the other point on the other side of (3,4). I am supposed to use only the slope of 2 to find these points. I cannot use the equation of the line even if I could find it. You are to use the slope of the line to find two points as desired above.
After someone finds a point, that point cannot be used by anyone else. Explain your procedure in using the slope to find your points.
Note: The slope of 2 can be written as 2/1 or as (-2) / (-1).
Answer by richard1234(7193)   (Show Source):
You can put this solution on YOUR website! If (3,4) lies on a line with slope 2, then (3+k, 4+2k) will lie on that line, for any k (do you see why?). Plug any number into k to obtain a point.
