Answer:
y=-1/3x-3
Explanation:
First, we should find the slope
The equation for slope is
where m is the slope and the x's and y's are points on the line.
Plug in points

Meaning the slope is -1/3
The slope intercept form is y=mx+b where m is the slope and b is the y intercept (so far the equation is y=-1/3x+b)
We can also find b by plugging in a point
For example, let's use point (-9,0)

Finally, to check, we can use point (6,-5)
