9x + 3y = 3; x = -2, -1,0

The equation y+=+-3x-1 is in the form y=mx%2Bb where m=-3 is the slope and b=-1 is the y intercept.

Step-by-step explanation:

9x%2B3y=-3 Start with the given equation

9x%2B3y-9x=-3-9x Subtract 9x from both sides

3y=-9x-3 Simplify

%283y%29%2F%283%29=%28-9x-3%29%2F%283%29 Divide both sides by 3 to isolate y

y+=+%28-9x%29%2F%283%29%2B%28-3%29%2F%283%29 Break up the fraction on the right hand side

y+=+-3x-1 Reduce and simplify

The original equation 9x%2B3y=-3 (standard form) is equivalent to y+=+-3x-1 (slope-intercept form)

The equation y+=+-3x-1 is in the form y=mx%2Bb where m=-3 is the slope and b=-1 is the y intercept.
