Pick any two of the points given. Let's use (0,3) and (3,3). Let's calculate the slope of the line:





Notice that no matter which pair of points you select, you will have a numerator of zero in the slope fraction, hence the slope is zero.

The line intersects the -axis at (0,3), hence the -intercept is 3.

Now we can use the slope-intercept form of the equation of a line to write the equation:





or more simply:
