I know that part

$$\text {  To  calculate   the   slope   of  a   line ,  use  the  formula}\  m=\frac{ y _{2}-y_{1} }{x_{2}-x_{1}}\  \text {  Here }  y _{2}=\  -3  \  \ \ and  y_{1}=3\\ x _{2}= 1\  \ \  \text {  and } x_1{-5}\\m=\frac{-3-3}{1-(-5)} =-1\\\text{ Then just substitute the slope In place of m,  and the value of  the} \\ \text{ y intercept In place of the equation   y = mx  + b    } \\(3)=(-1)*(-5)+b \  b=-2\\   y=-x-2$$

So -2 is the correct answer ?

Ok I thought that was the answer but wasn't sure I was doing it correct, so thank you.
