Final answer:
The equation y = 3x + 6 is already in slope-intercept form.
Step-by-step explanation:
The equation equivalent to y = 3x + 6 when written in slope-intercept form is y = 3x + 6. In slope-intercept form, the equation is written as y = mx + b, where m is the slope and b is the y-intercept. The given equation already follows this format, so it is equivalent to itself.
