You can put this solution on YOUR website! Hello!
Given two points (x1, y1) and (x2, y2), the slope of the line that passes through them is very simple to find. Just use this formula:
In this case, however, the slope of this line would be infinite, because the line that passes through the points you mentioned is vertical (notice that the x-coordinate is the same for both points).
If there is a typo in the points you stated, just use the formula I gave you witth the correct values in order to find the slope of the line.
I hope this helps!
