Question

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?

Answer 1

Question 17:

An equation for horizontal lines has the form:

$y=m$

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
