As per the statement:
Slope of a line is 2/3.
Here x axis represents the lesson length in minute and y axis represents the money billed in dollars
Then;
Slope of a line represents the money billed per lesson length.
You have to divide the 5 and 5x by 5 add your variables together in alpha order=1
480/6 is 80.
80 x 5 is 400.
So there are 400 girls.
