Answer:
[tex]5 = - 2x - y[/tex]
To find this you must find the slope first:
[tex] \frac{y - y1}{x - x1} [/tex]
which is, after performing some calculating is -2.
Next you need to set up your eqaution:
[tex]y - y1 = m(x - x1)[/tex]
when you set it up, and substitute the variables for your slope and points you should get this:
[tex]y - ( - 3) = - 2(x - 1)[/tex]
[tex]y + 3 = - 2x - 2[/tex]
add 2 to both sides
[tex]y + 5 = - 2x[/tex]
subtract y from both sides
[tex]5 = - 2x - y[/tex]
