Question
does every horizontal line have an x-intercept? why or why not?

Answer
Hello, Chel.

Horizontal lines do not have x-intercepts. Horizontal lines do not pass through the x-axis; they only pass through the y-axis.

A horizontal line which passes through the point (0,5) is equal to
y = 5.

Hope this helps.

Regards,
John
