Question 807136
You need two points on the line in order to graph it, but first get the equation in slope-intercept form: y = mx + b
---
3y = -9x + 9
y  = -3x + 3
---
Plug-in two different x values in the equation to get their y values, like so: 
Point p1, use x=0:
y = -3(0) + 3
y = 3
p1 = (0, 3) 
Point p2, use x=1:
y = -3(1) + 3
y = 0
p2 = (1, 0) 
Now draw a line between points p1 and p2 to graph the equation. 
The line extends infinitely beyond both points.
