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
First, you have to write it in a form of y = mx + b :
When both lines are parallel to each other, they will have to same gradient value. So the equation of the line is y = (-2/5)x + b. Next, you have to find the value of b by substutituting (-10,3) into the equation :
