Answer
Fill the blanks with
... infinitely many ...
... $1-t$ ...
.. 0 ... 4 ... $-4$
Work Step by Step
Solving for y, each equation is equivalent to
$y=1-x$.
Since both equations have the same graph,
there will be infinitely many solutions ( the system is dependent ).
Taking x as a parameter, x=t
these solutions can be expressed by writing
$x=t$
$y=1-t$
If t=1, y=0
If t=-3, y=$1-(-3)=4$
If t=5, y=$1-5=-4$
Fill the blanks with
... infinitely many ...
... $1-t$ ...
.. 0 ... 4 ... $-4$
