3. Which of the following equations represents a line that does not intersect the x-axis?
Explain your answer.
a. x = 4
b. y =-5
C. y = 2x - 4
d. 3x - 8y = 17
b. y=-5 when graphed is a straight line parallel to the x axis. Knowing the definition of parallel lines we can conclude that y=-5 and the x-axis never intersect
