The percentage of Male workers who prefer a female boss over a male boss increased approximately linearly from 5% in 1974 to 9% in 1998. Predict when 9% of male workers will prefer a female boss.

1998

y=6x+1944

Step-by-step explanation:

from the question we know that 9% of male workers prefer female boss in 1998. but we can predict a model for this by getting the slope of the graph  first, then slotting into equation of a line graph

y=the year

x=the percentage of men who prefer a female boss

s=y2-y1/(x2-x1)

s=1998-1974/(9-5)

s=24/4

s=6

so from equation of a linear graph

y=mx+c

y=6x+c1

when y=1998,x=9

1998=6(9)+c

c=1944

from equation 1

y=6x+1944

expression #3 is not equivalent. the others are.
