Since you already have the slope, you just have to plug in the points in the equation
![y- y_{1} =m(x- x_{1})](https://tex.z-dn.net/?f=y-%20y_%7B1%7D%20%3Dm%28x-%20x_%7B1%7D%29%20)
Just plug in the number in for y1 and x1 and you'll get:
![y+2 =3(x-1)](https://tex.z-dn.net/?f=y%2B2%20%3D3%28x-1%29)
Which is C!
