#"For no "k," any line that passes through the points"#

#(-2,3)" and "(-1,k)" can have slope "k#.

Explanation:

The slope of line through the points #(-2,3) and (-1,k)# is

#(k-3)/(-1-(-2))=(k-3).#

But, this slope is given to be #k#.

#:. k-3=k rArr -3=0," which is impossible"#.

#:. "for no "k," any line that passes through the points"#

#(-2,3)" and "(-1,k)" can have slope "k#.
