You can put this solution on YOUR website! describe how to draw a line that passes through the origin and has a slope of minus two thirds.
-----------
Plot 2 points.
(0,0) is one.
m = diffy/diffx = -2/3
--------
From (0,0) count 3 units to the right (for x) and 2 units down (for y).
--> the point (3,-2)
Draw a line thru them.
===================
Another way is to use the equation:
y-y1 = m*(x-x1) where (x1,y1) is the point (0,0)
y = m*x = (-2/3)x
y = -2x/3
=============
Pick any value for x, find y, plot the point.
