Question 100700
describe the resulting graphs by identifying the vertex point, the graphs direction and any axis intercepts gleaned from the table or graphs 
y = -x + 1
-------------------
That equation graphs as a line; it has no vertex.
y-intercept:
Let x = 0, then y = 1 is the y-intercept
--------------
x-intercept:
Let y = 0, then x = 1 is the x-intercept
---------------
{{{graph(400,300,-10,10,-10,10,-x+1)}}}
