Well, the slope of this line would be -2.
So, You need to find what the Y intercept is. (I'm sorry but I do not know what that is)
Once you have the Y intercept, your equation would look like this:
Y= -2x + (or -) your y intercept.
If you have a y intercept that is negative, it would be minus and if your y intercept is positive, it would be plus.
The original equation without numbers is y=mx+b
M= the slope
B= the y intercept
I really hope this helped you :)
