This question will require the understanding of "standard form".
x+y={number}
TO SOLVE:
We will first need to find the slope. The slope can be determined by:
[tex]\frac{y^{2}-y^{1}}{x^{2}-x^{1}}[/tex]
So our equation will be:
[tex]\frac{-4-1}{2+1}[/tex]
The slope will be -5/3. Now, let's solve the y-intercept also known as (0, y). To find this, we will just plug in our numbers. (I'd like to do this in y-intercept form)
y=mx+b
To solve, we will take either of the points. I'll choose (-1, 1) as it is easier.
1=-1(-5/3)+b
1=(5/3)+b
-2/3=b
So, our slope intercept form will be:
y=-5/3x-2/3.
We will convert it by subtracting x from both sides.
So thus, 5/3x+y=-2/3 is the answer!
