1) The y-intercept is the point where the line intercepts, or meets, the y-axis. This is at the point (0, 600).
2) Conversely, the x-intercept is the point where the line intercepts the x-axis. This is at the point (900, 0).
3) [tex]\frac{600-0}{0-900}=\frac{6}{-9}=-\frac{2}{3}[/tex] As you can see, the y and x coordinates are set up accordingly in this equation. The points used are (0, 600) and (900, 0).
4) Based on the above, the function here is y = -2/3x + 600
Hope this helps, let me know if I messed up!
