Slope of the line through the points (-5, -3) and (-5, 2)



m+=+%28y%5B2%5D+-+y%5B1%5D%29%2F%28x%5B2%5D+-+x%5B1%5D%29


m+=+%282+-+%28-3%29%29%2F%28-5+-+-5%29


m+=+%282+%2B+3%29%29%2F%28-5+-+-5%29


m+=+%285%29%2F%280%29


Since you CANNOT divide by 0, this means that the slope of the line is undefined.


Answer: The slope of the line is undefined.

The slope of a line is rise%2Frun which is the change in Y divided by the change in X. Since they are giving you 2 points through which the line goes, you can find the slope as follows:
%28y2-y1%29%2F%28x2-x1%29
Which for the 2 given points, is:
%282-%28-3%29%29%2F%28-5-%28-5%29%29
Simplifying this gives you a zero in the denominator, which means the slope of this line is infinite - i.e. it is a vertical line (a line parallel to the Y-axis).
Good Luck,
