5 pencils and 7pens together cost $50, whereas 7 pencils and 5 pens together cost $46. Find the cost of one pencil and that of pen.

The below image is

Correct option is (d).
Reason ; In the given graph , on moving owards x axis from 1 to 4 there is change of there is change of 1.5 unit  on y axis but on further movement from point 4 to 8 there is small change of .5 units on y axis .it shows that there is very small and non constant change  on y axis hence the graph shows non linear realtionship
