Determine if (-1,-3) is a
solution to the equation
y = 1 + x
we know that
If a ordered pair is a solution of a equation, then the ordered pair must satisfy the equation
so
For x=-1 and y=3
substitute in the equation
3=1+(-1)
3=0 ----> is not true
that means
the ordered pair not satisfy the equation
therefore
Is not a solution
