To determine the y-intercept of the equation \( y = x - 1 \), we need to find the value of \( y \) when \( x = 0 \).
Substituting \( x = 0 \) into the equation:
\[
y = 0 - 1 = -1
\]
So the y-intercept is \( -1 \).
The ordered pair for the y-intercept is \( (0, -1) \).
Therefore, the correct option is:
**Option two: the y intercept is one with an ordered pair of (0, -1).**
Substituting \( x = 0 \) into the equation:
\[
y = 0 - 1 = -1
\]
So the y-intercept is \( -1 \).
The ordered pair for the y-intercept is \( (0, -1) \).
Therefore, the correct option is:
**Option two: the y intercept is one with an ordered pair of (0, -1).**
