please help!!

a) A T vs. m graph looks like the following diagram. Straighten this graph by using the table provided. m Period "T" Period "T" ( kg) (s) (5) 0.5 8.90 8.90 1.0 12.60 12.60 1.5 15.40 T 15.40 2.0 17.80 17.80 2.5 19.90 19.90 3.0 21.80 21.80 3.5 23.50 m 23.50 b) What is the slope of the straight line graph? Ignore units. c) If the phenomena is described as T' = 4/ Vm , what should your slope equal for the straight line graph? Ignore units
