Answer 1

Numbers 5 7 and 8 on the last page of the pdf, to be more specific.

Answer 2

5) The answer is C. k = 3.... Product of slopes should be -1(the lines are to be perpendicular) and slope of 6x-4y =12 is 3/2 and slope of perpendicular line is -2/3 which is possible iff k(coefficient of x) is 3....
