Question 53937
y=-x+1
Plot some points.  Let x=-1, then:
y=-(-1)+1
y=1+1
y=2
Plot (-1,2).
------------
y=-(0)+1
y=0+1
y=1
Plot (0,1)
------------
y=-(1)+1
y=-1+1
y=0
Plot (1,0)
-------------
Conect the dots, and it should look like this:
{{{graph(300,200,-10,10,-10,10,-x+1)}}}
Happy Calculating!!!!
