Question

What is the equation of the line?

Answer 1

Answer:

y=4

Step-by-step explanation:

Since the slope is constant, and the only y value for each x value is 4, then the equation is y=4.

Answer 2

Answer:

y=4

Step-by-step explanation:

It's 4 on the y axis! There is no line intersecting with points on the x axis.

This type of slope is often confused with vertical lines! Vertical lines are always undefined. Horizontal lines are simply 0. You cannot use RISE/RUN, because you can only go one way on the line, right/left.

I hope this helps and made sense!
