the following table gives the force F newtons which, when applied to a lifting machine overcomes a corresponding load of L newtons.
Force F newtons 25 47 64 120 149 187
Load L newtons 50 140 210 430 550 700
choose suitable scales and plot a graph of F (vertically) against L (horizontally) Draw the best straight line through the points. Determine from the graph (a) the gradient (b) the F-axis intercept (c) the equation of the graph (d) the force applied when the load is 310N (e) the load that a force of 160N will overcome (f) if the graph were to continue in the same manner, what value of force would be needed to overcome a 800N load?
this is how i have plotted the graph
from this i have worked out questions (a)(b)(d)(e)
if you think that any of these are wrong please tell me
i need help on (c) & (f)
