Solution

The graph of the different permutations between TV and refrigerators is given below

Let y be the number of TVs and x be the number of refrigerators

Answer of Q. 68 (a)

A line is passing through (0,330) on the y axis and through (110, 0) on the x axis. Slope of the line is

Slope = 330 - 0/ 0-110 = -330/110

Slope = -3

Hence equation of the line becomes

Y = -3x + b

Hence any change is x would bring a negative change of 3 in the y axis.

Now considering the point on the y axis at ...
