Make 1 1/5 into improper fraction which is 6/5 and then find the common denominator 6/5 and 5/8.
Common denominator is 40. Multiply 8 by 6 and 8 by 5 so it would become 48/40. Do the same with 5/8 except multiply by 5 which would be 25/40. Subtract 48/40 and 25/40 which is.....
23/40
The y intercept (when x=0) is 40
the slope is 15 ( slope= rise/run= 15/1=15)
therefore, the equation of the line is y=15x+40
It's basically multiplication by 3. 3x3 9x3 27x3 etc
