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)
