<PRE><B>Question 150105</B>
If $20  in Australian currency converts to $10.50 in American (or US) currency, draw up a graph showing the relationship between the two currencies. (Hint: What is $A0.00 equivalent to in $US?)
----------
You have two points: (0,0) and (A20,10.5)
Plot the two points and draw a line thru them.
---------
slope = 10.5/20 = 0.525
intercept = 0
------------------------
{{{graph(400,300,-10,50,-10,50,0.525x)}}}
--------------------------
The horizontal axis is Australian value; the vertical is US.
