Answer:
-11
Step-by-step explanation:
There is enough information to put the equation in point slope form.
[tex]y-y_1=m(x-x_1)[/tex]
We are given the point of (-5,4) and the slope of -3.
[tex]y-y_1=m(x-x_1)\rightarrow \boxed{y-4=-3(x+5)}[/tex]
Now, we can take the point slope equation and convert it into slope intercept form.
[tex]y-4=-3(x+5)\\\\\left \{ {{-3*x=-3x} \atop {-3*5=-15}} \right.\\\\ y-4=-3x-15\\\\y-4+4=-3x-15+4\\\\\boxed{y=-3x-11}[/tex]
The y-intercept should be -11.
