<PRE><B>Question 859774</B>
 How would you do the following problem: sketch a rectangular coordinate system, and graph the line y= 1/2x -1? 
----
The y-intercept is -1, so put a point at (0,-1)
The slope is 1/2, so y increases 1 when x increases 2.
Move 2 to the right of (0,-1) and 1 up to the point (2,0)
-----
You now have two points.  Draw a line thru them.
{{{graph(400,400,-10,10,-10,10,(1/2)x-1)}}}
