First you would add together the ratios which equals 9. Then divide 1,800,000 by 9 giving you 200,000.Then you would multiply 200,000 by each ratio individually giving you the answers. which would be 800,000:600,000:400,000
By looking at the graph you can rule out choices C and D because the graph given to you is an increasing linear function and C and D represent functions with a decreasing or negative slope.
By looking at the picture the slop of the graph seems to be 4/1 (rise/run) so your slope is 4. And your y-intercept looks like its -4 so your answer is B<span />
