Question 422648: A line contains the points (1,-3) and (1, -2). Another line graphed in the same coordinate plane contains the points (-2,0) and (-3,-3).
Based on the slope of these lines, are they parallel, perpendicular or neither?

You can put this solution on YOUR website!
The slope of a line is (change in y)/(change in x)
given:
(1,-3) and (1,-2)
slope =+%28-2+-%28-3%29%29+%2F+%28+1+-+1%29
slope = +1%2F0+
division by 0 means the line is vertical (infinite slope)
and
(-2,0) and (-3,-3)
slope = +%28-3+-+0%29+%2F+%28-3+-%28-2%29%29+
slope = +-3+%2F+-1++=+3+
They are neither
