How?

sleepyjess · Answer

You need variable N when variable M equals 50. You said that you know one is (20, 70). That isn't making sense in my mind

Ya on the graph you can see a line going threw the dots, i have to get that dots and do the y2 - y1  and times in the the 50 into x
      ------- 
       x2 - x1
