Question 560646
to find the slope you divide 7.25 by 9 which is rise/run.

7.25/9=0.85555556

then put the known values in y=mx+b form.
put 7.25 in for x, .85555556 in for m, and 9 in for x

then you have      7.25=(.8555555*9)+b
                   7.25=7.25+b
                  -7.25 -7.25
                   0=b
lastly put 0 in for b and .85555556 in for m

the final equation is y=.85555556x+0 or y=.85555556x
