of lines in the advertisement. The table shows the total cost for different length advertisements in the Daily
Times. The total cost y (in dollars) for an advertisement that is x lines long at the Greenville Journal is

The newspaper that charges less per line is Greenville Journal and the line of the advertisement must be 5 for the cost to be the same

How to determine the newspaper that charges less per line?

We have:

Greenville Journal is represented by the equation

y = 2x + 20

For Daily times, the rate is

Rate = y2 - y1/x2 - x1

This gives

Rate = (30 - 27)/(5 - 4)

Evaluate

Rate = 3

For Greenville Journal's equation y = 2x + 20, the rate is

Rate = 2

This is so because the slope is 2

By comparison 2 is less than 3

Hence, the newspaper that charges less per line is Greenville Journal

When they cost the same

The equation of Daily times is

y = m(x - x1) + y1

So, we have

y = 3(x - 4) + 27

Evaluate

y = 3x + 15

Substitute y = 3x + 15 in y = 2x + 20

3x + 15 = 2x + 20

Evaluate

x = 5

Hence, the line of the advertisement must be 5 for the cost to be the same
