Question 807136: how do you graph 9x=-3y+9
Answer by TimothyLamb(4379)   (Show Source):
You can put this solution on YOUR website! 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.
