this question is on linear law. for this topic, the basic idea is to re-arrange the given equation into the form ...
Y = mX + c,
which gives a straight line when Y is plotted against X.
from the graph, we get the gradient m & y-intercept c
which can be used to work out the unknown constants.
for part(iii), you need to rearrange the new equation into the same form as what you obtained for (i), so that you can plot onto the same axes and find the intersection point.
