<span>Ratio!
Two different numbers are considered proportional if they have the same ratio.
Let’s have an example:
=> I the price of an apple is 2 dollars,
=> then the price of 10 apples are 20 dollar
=> the price of 100 apples are 200 dollars
=> the price of 150 apples are 300 dollars.
And so on…. As long as their values are related, they are proportional.
another example:
=> my hair grows 5 inches in 1 month
=> it grows 10 inches in 2 months</span>
Create equations:
10X+15y=2575.
X+Y=210.
Solve for X: X=210-Y, and sub it into the other equation: 10(210-Y)+15Y=2575. Solve for Y: 2,100-10y+15y=2575, 5y=475, y=95.
Sub Y into the original problem: X+95=210. Solve: X=115.
The first mechanic charges $115 per hour and the second charges $95 :)

You just need to make a line with the most dots that you can. Make the most dots you can fit on one line from the 0 to the end of the graph diagonally and fit as many points as you can. <span />
