Answer:
y= -1/3x - 2/3
Step-by-step explanation:
y- intercept is (0, -2/3) and the x intercept is (0, -2).
To find the slope of an equation, you do rise over run. To get from (0, -2/3) to (0, -2), you rise 2/3 and run -2. 2/3 divided by -2 is -1/3, that is where you get the slope from.
Set up a proportion:

=

To solve cross multiply:
3000x=300000
divide both sides by 3000:
3000x/3000=300000/3000
x=100
