Answer
The solution is $(0,-5)$.
Work Step by Step
The given system of linear equation is
$4x-4y=20$ ...... (1)
$y=-5$ ...... (2)
Graph each equation.
The intersection point is $(0,-5)$.
Check the intersection point.
Equation 1:
$\Rightarrow 4x-4y=20$
$\Rightarrow 4(0)-4(-5)=20$
$\Rightarrow 0+20=20$
$\Rightarrow 20=20$
True.
Equation 2:
$\Rightarrow y=-5$
$\Rightarrow -5=-5$
True.
The solution is $(0,-5)$.
