in a making a graph showing the stretch of a spring: Plot a graph of force vs. stretch. Find the slope. The Slope of the graph is called the spring constant. 1)What does the slope of the graph tell you? 2) If someone had a graph with a slope twice as stee...

I'm making a graph of force vs stretch for springs. I have 7 data trials with the k (F = kx) ranging from 28 to 31, average is 29.6. Now I need to find the slope and write an equation for the graph. If I use the first two points to get the slope, I get a...
