What is the slope of the line with equation y4x?

The equation you provided, "y4x," seems to be a typographical error. If you meant to write it as (y = 4x), then the slope of the line is 4. In the slope-intercept form (y = mx + b), (m) represents the slope, so in this case, the slope is 4. If you meant a different equation, please clarify for an accurate answer.
