Question 98365
make a graph to depict the variables for the value of a house that is $10,000 now and rises $1500 every year. 
------------------
Let "now" be represented by x=0
That gives you a point: (0,10000) which is the y-intercept.
---------------
When x = 1 the value is 10000+1500 = 11500
That gives you a point: (1,11500)
---------------
With two points you can find the slope:
m= (11500-10000)/1 = 1500
-----------------------------
You now have the slope and the y-intercept.
EQUATION:
value = 1500x + 10000
===============
{{{graph(400,300,-5,10,-5,30000,1500x+10000)}}}
