The equation \( y = 5x - 4 \) is already in the slope-intercept form, which is \( y = mx + b \), where \( m \) is the slope and \( b \) is the y-intercept.
In this case:
- The slope \( m \) is \( 5 \).
- The y-intercept \( b \) is \( -4 \).
So, the equation is in the correct format \( y = mx + b \).
