An npn transistor is correctly biased and turned on if the a. base is negative. b. collector is negative. c. collector is positive with respect to the emitter and negative with respect to the base. d. collector is the most positive lead followed by the base.

Graph A

Explanation:

we need to find the slope using the slope formula y2-y1/x2-x1

Graph A:3-0/4-0

               3/4

Graph B: 4-0/4-0

                   1

Graph C: 5-0/4-0

              5/4

Graph D 8-0/4-0

                 2

These slopes are the cost per pound of apple and graph A has the smallest slope
