17. An equation for horizontal lines has the form: ___________ and is parallel to the ______ − axis.18. If you were to draw a horizontal line on the x−axis, the equation of the line would be y= 0. Explain why this equation is a logical conclusion?

Question 17:
An equation for horizontal lines has the form:
[tex]y=m[/tex]and is parallel to the x-axis
Question 18:
If you were to draw a horizontal line on the x−axis, the equation of the line would be y= 0. Explain why this equation is a logical conclusion?
Because it will represent the x-axis, all the points lying on the line will have
y-coordinates = 0
