Question 366609: Find the slope if it exists, of the line containing the points [-1 1/2] and [-10 1/2]
Answer by josmiceli(19441) (Show Source): You can put this solution on YOUR website!
The points are in the format (x1,y1) and (x2,y2).
Notice that y1 = 1/2 and y2 = 1/2
If there is no change in y for any 2 points on a line,
then that line has to be vertical, or slope = infinity
the equation of the line is
