Question

As the number of billboards for a firm's product increases from 100 to 500, its sales increase from $1,000 to $10,000. If this information is plotted on a line chart, the slope of the line equals ________.

Answer 1

Answer:

0.444

Explanation:

Formula for slope = (X2 - X1)/(Y2 - Y1)

X1 =100

X2 = 500

Y1 = 1000

Y2 = 10000

Slope = (500 - 100)/(10000 - 1000)

=400/9000

=4/90

=0.04444

Number of bill(X axis) against sales (Y axis)
