Can I please get help making this graph and answer a few questions please?

For the graph would you please mind giving me a brief analysis of it?

need graph using the data in Extension Activity Data Table 3 of velocity, v, vsWavelength, l (v vs l). {Note: variables are identified for graphing as y vs x} On the graph insert a best fit line and display the equation on the graph (title the graph, label the axis with quantity and units). Consider whether the data point (0, 0) should be included on your graph; include the point (0, 0) if it is in agreement with the experiment and relationships between the variables.

5. The slope of the line on your Extension Activity Data Table 3 graph is the experimental fixed frequency value used to establish standing waves on the string with a mass per unit length m = 3.313 x 10-4 kg/m. Calculate the % difference between the slope of your line and the average frequency calculated in Extension Activity Data Table 3. 6. For most experiments an acceptable error is 5% or less; is the % Difference calculated for the frequency in Extension Activity Data Table 3 within an acceptable % error
