Step-by-step explanation:
1. Analyze: There are 60 people total and there is 5x more pants than skirts. This outrules 60 and 50.
2: Testing put all of your numbers into an equation. Since you need the total to be 60 you can do this. I am using p(pants) S(skirts for my example. S+S5=60 10 works in this equation.
The line crosses the x -axis at point (9,0) and the y-axis at point (0,6).
If the equation of the line is
then substitute the coordinates of the points into this equation:
1) 
2) 
Substitute the second equation into the first:

The equation of the line is
