Question 79790
The slope of a line is {{{rise/run}}} 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:
{{{(y2-y1)/(x2-x1)}}}
Which for the 2 given points, is:
{{{(2-(-3))/(-5-(-5))}}}
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,
