Question 422648
The slope of a line is (change in y)/(change in x)
given:
(1,-3) and (1,-2)
slope ={{{ (-2 -(-3)) / ( 1 - 1)}}} 
slope = {{{ 1/0 }}}
division by {{{0}}} means the line is vertical (infinite slope)
and
(-2,0) and (-3,-3)
slope = {{{ (-3 - 0) / (-3 -(-2)) }}}
slope = {{{ -3 / -1  = 3 }}}
They are neither
