The table below shows experimental values of two variables x and y which are related by the equation y = kx, where k and t are constants. 1.5 2 2.5 3 4.5 y 45 25 15.8 11 2.6 (1) Plot a straight line graph of Ig y against lg x. (ii) Use your graph to estimate the value of k and of t. (iii) On the same diagram, draw the line representing the equation y = x' and hence find the value of x for which x = k.
