Find the slope of the line through the following pairs of points.\r
\n" ); document.write( "\n" ); document.write( "(-5, -3) and (-5,2)
\n" ); document.write( "This is a special case. Notice that the x values of both points (x,y) is -5. If we were to plot the points and connect them, we would have a vertical line going through x=-5. Vertical lines have undefined slopes.
\n" ); document.write( "If you tried to find it using the slope formula this is what happens:
\n" ); document.write( " $\"highlight%28m=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29%29\"$ , m=slope, (x1,y1) and (x2,y2) are the given points.
\n" ); document.write( "In this case, (x1,y1)=(-5,-3) and (x2,y2)=(-5,2)
\n" ); document.write( " $\"m=%282-%28-3%29%29%2F%28-5-%28-5%29%29\"$
\n" ); document.write( " $\"m=%282%2B3%29%2F%28-5%2B5%29\"$
\n" ); document.write( " $\"m=5%2F0\"$ <---this is undefined, you can't divide by 0.
