Question

graph the system of linear equations on your calculator and select the solution

Answer 1

we are giving the equations

$y=-3x-15\text{ }and\text{ }y=-12$

since y=-12

let's replace in the first equation

$-12=-3x-15$$-12+15=-3x$$3=-3x$$x=-1$

then the solution to the point (x,y) is

Option C

(-1,-12)
