we can conclude that the line is a horizontal line because both points share the same y value.
since the line is horizontal and every point on that line will have a y value of -4, the equation is y=-4
finally, the slope of this line IS zero. this is because the line is a horizontal line and all horizontal lines have a slope of zero.
hope this helped!
