You have to remember the Slope-Intercept Rule. That's 𝐘 = 𝐦𝐗 + 𝐛. m= the slope of the line. And b = where it crosses the Y-axis. In your case, m has a value of 3 and so does b. So your line's slope is 3 and it crosses the Y-axis at (0,3).

If you mean y = 3x + 3 then it is a straight line equation whereas the slope is 3 and the y intercept is 3
