Question 672417
The slope is ( change in y ) / ( change in x )
(-2,4) and (-2,6)
slope = {{{ ( 6 - 4 ) / ( -2 -(-2) ) }}}
slope = {{{ 2 / 0 }}}
This is infinite slope, meaning a vertical line.
---------------
(-25,4) and (-2,8)
slope = {{{ ( 8 - 4 ) / ( -1 -(-25) ) }}}
slope = {{{ 4 / 24 }}}
slope  = {{{ 1/6 }}}
This slope is oblique to a vertical line
