This is a linear relationship because:

(20-10)/(4-2)=(35-20)/(7-4)=m=5

So we have a line with a slope of 5, and the slope intercept form of a line is:

y=mx+b, and we have found that m=5

y=5x+b, now using any point we can solve for b, use (2,10)

10=5(2)+b

10=10+b

0=b so the line is:

y=5x  
proportional is the answer
