You can put this solution on YOUR website! To find slope of line when given two points use this formula:
just plug in the x and y values of the points given
perform operations
So the slope of a line containing the points (-6,4) and (5,4) has a slope of zero. If a line has a zero slope that means it is a horizontal line. Also when you see that two points on a line have the same y coordinate this should clue you in that it is a horizontal line, and horizontal lines always have a slope of zero.
Graphing the line we can see this to be true.
