What is the y-intercept in the equation y = (1/3)x + 3?
The Y-intercept is 3.
You have a slope intercept equation here- y=mx+b. With m representing the slope and b representing the y-intercept. Therefore, with the equation y=(1/3)x+3, your slope is going to be 1/3 (rise over run) and your y-intercept is going to be positive 3.
