Question #8ebbc
1 Answer
The method is the same as any other graph :
The gradient
Explanation:
The method is the same as for finding the gradient (or slope) of any other graph:
1. Choose two points that are on the line, point 1 and point 2.
2. Those points will have coordinates (
3. The gradient
It may be that the question is actually about the analysis of a distance v. time² graph. If so, in order to answer the question the equation that is part of the question needs to be shared (the equation might be
If the equation is as above the method of analysis is as follows:
1. Compare the equation that is given to
2. Identify x and y from what is plotted on the x and y axes. In our case (distance v. time² ) it would be distance on the y-axis and time² on the x-axis.
3. Everything multiplied by the "x" term would be equal to the gradient. In our case we can then write: gradient
4. The separate term in the equation is equal to the y-intercept. In our case it would be: intercept
5. Use the gradient and intercept values determined from the graph to solve for the unknowns. In our case those are
