Answer the question.Does every straight line have an x-intercept? If not, give an example of an equation whose graph does not have an x-intercept.
What will be an ideal response?
The x-intercept is the point where the line crosses the x-axis. Lines parallel to the x-axis do not intercept the x-axis. Thus the graph of any equation of the form 
where 
has no x-intercept.
