Y=6
Notice that the two points both have a y-coordinate of 6. This tells us that the line will be horizontal meaning that it will have a ZERO SLOPE. Zero slope means that there will be no “x” in the equation because “x” indicates that there is a slope. So if it’s a horizontal line that goes through the y-value of 6, that means the graph has a y-intercept at y=6 which is also the equation of the line.
