The equation \( y = x + 3 \) represents a straight line in the form of \( y = mx + b \), where:

- \( m \) is the slope of the line, which in this case is \( 1 \) (since there is no coefficient in front of \( x \), it's assumed to be \( 1 \)).
- \( b \) is the y-intercept, which is \( 3 \) (the constant term).

This means the line crosses the y-axis at \( (0, 3) \), and for every increase of \( 1 \) unit in \( x \), \( y \) increases by \( 1 \) unit.
