Definition
 Rearrange the equation to the form y = mx + b.
 Figure out how the slope and yintercept relate to the constants.
 Draw a best fit line.
 Calculate the slope and yintercept from your line.
 (If needed) calculate the slope and yintercept.
For example, in this problem 1/b = slope and a = yintercept.

Definition
 Find the data point where F = 30 N.
 Figure out if you're using vertical or horizontal error bars.
 Determine how long the error bars are at F = 30 N.
 State answer with correct units.
In this case, the units would be m/s because you're finding the absolute uncertainty in speed. You'd use the vertical error bars.

Definition
 Find the data point where F = 20 N.
 Find the percentage uncertainty in that point.
 Determine the value of v.
 Determine the value of ∆v (use the error bars).
 Calculate ∆v/v.
 Multiply the percentage uncertainty by 2.5 (the exponent).
 Calculate the absolute uncertainty in v^{2.5}.
 Calculate the value of v^{2.5}
 Use the equation % in v^{2.5} = ∆(v^{2.5})/v^{2.5}

Definition
Some rules to follow:
 Your line can be straight or curved.
 Send the line through all of the error bars.
 Extend your line all the way back to the y axis.
 If you can send the line through the origin, do that.
 If your line is curved, make sure it's smooth & not bumpy.

Definition
 Rearrange the equation to the form y = mx + b.
 Determine what the slope and yintercept are.
 State how the slope & yintercept are related to the constants. (Ex: b is the slope & a is the yintercept.)
 Draw a max slope line and a min slope line.
 Calculate the max & min values of slope/yintercept.
 Use: absolute uncertainty = (max – min)/2
