Answer: m = 0
Step-by-step explanation: To solve this problem, we don't even have to use our slope formula. It's important to understand that when we have the same y coordinate in our first ordered pair and our second ordered pair, this means that the line will be flat or horizontal.
When a line is horizontal, it means the line has a slope of zero.
We use the variable m to represent slope.
So here, we can say that m = 0.
