To express the fact that a 16-line ad costs $86 as an ordered pair, we start with the equation for the cost of the advertisement:
\[
y = 4x + 22
\]
Here, \( x \) is the number of lines, and \( y \) is the total cost in dollars.
For a 16-line ad, we have \( x = 16 \). We can substitute this value into the equation to find \( y \):
\[
y = 4(16) + 22
\]
\[
y = 64 + 22
\]
\[
y = 86
\]
Now, we have the values of \( x \) and \( y \). Thus, the ordered pair representing the number of lines and the cost is:
\[
(16, 86)
\]
So, the ordered pair is **(16, 86)**.
\[
y = 4x + 22
\]
