Answer:
y=3x+3
Explanation:
The +3 at the end is the y-intercept, that's where the line crosses the y-axis. The 3x is the slope, and you can easily find the slope by doing the RISE OVER RUN METHOD. Pick any point where the line crosses the x-axis, then count up, RISE how many times it goes to the next crossing point, then count over, RUN, how many times it goes to the next crossing point.
