Case 2: Next, consider the case of a student wishing to determine the spring constant for a spring by measuring the period of oscillation of a mass on the spring. The student knows that the relationship between the spring constant (k), the mass (m), and the period of oscillation (T) is given by the equation m T = 2n. (18) V k This is not a linear equation, but it can be linearized using the same method used to linearize Equation 10. Square both sides of the equation. Then, you can then plot T² versus m. The slope of the resulting line can be used to determine the spring constant, k. Mass (m) 0.200 kg 0.400 kg 0.600 kg 0.800 kg 1.000 kg 1.200 kg Period (T) 0.331 sec 0.459 sec 0.575 sec 0.669 sec 0.728 sec 0.803 sec T2

So I am doing this practice lab and I think I am just overthinking it for my step number 6. I sure it is as straight forward as it shows but I am just not understanding. So for "r" I have 84.7 cm which is 0.847 m for my first measurement. I think all I have to do is just input it to the formula provided that I have in the photo for step 6. So if i can just get a better example of what it is asking, I would greatly appreciate. I am just slow when it comes to following instructions.

The graph below illustrates a driving trip from the town of Goodfield to the town of Peoria. distance (in miles) 35 30 25 20 15 10 5 0 0 0.25 0.5 0.75 1 time (in hours) (a) How far apart are the two towns? miles (b) Find the slope of the linear graph. select units (c) What does the shape of the graph tell us about the trip? ---Select---

I am a little confused on this question , please help. Thank you for your time!   I have attached the problem .Please view attachment before answering. Thank you again!
