The slope is $0$ and the y-intercept is $3$.
Work Step by Step
The equation of this line only has a y-intercept (the constant term in this equation), which implies that there is no slope. If there is no slope, the slope is actually $0$. Rewriting this equation in slope-intercept form, we can clearly see the values for the slope and intercept: $$y = 0x + 3$$ We can see that the slope is $0$ and the y-intercept is $3$.
