Answer: m = 0
Step-by-step explanation: To find the slope of the line that passes through these points, we would use our slope formula.
However, there is an easier way to do this problem.
Notice that in each ordered pair, our y-coordinates are -9.
Whenever we have the same y-coordinates, and different x-coordinates, the slope of the line will always be 0. If we had the same x-coordinates, there would be no slope since you can't divide by 0.
So since we have the same y-coordinates and different x-coordinates, we can conclude that this line has a slope of 0.
The variable that's used to represent slope is m.
So for this line we would say that m = 0.
If you did use the slope formula, you would end up with 0 as your numerator and 6 as your denominator and this simplifies to 0.
