If you are trying to find the equation for a line passing through those points, first we subtract the points.
(4,-1)
-(3,-2)
(1, 1)
Then we find out what our slope (m) would be by Rise (y) over Run (x)
1/1 = 1
y = mx + b is our equation for lines. M is the slope. Now we solve for B, by plugging one of our points into the equation.
-1 = 1(4) + b
-1 = 4 + b
-5 = b
Now that we have B, we have our full equation. y = x -5. Hope this helped!
