First, let's recall the slope formula:
, where y2 and y1 are y-coordinates; x2 and x1 are x-coordinates.
Plugin the values:
.
Upon simplifying, we obtain
.
Upon simplifying this further, we obtain
.
0 divided by anything results in 0.
✨ ∴, the slope of this particular line is 0, and this line looks something like this:
.
See, it's a horizontal line, with a rise of 0, meaning that it goes up 0 units.
