Question 672417: a/)what is the slope of the line that passes through points (-2,4)and (-2,6)?
show work supporting your answer.
b.)based on the slope you found in a is the line through(-25,4) and (-2,8) horizontal,vertical or oblique?

thank you so much in advance!!!!!

You can put this solution on YOUR website!
The slope is ( change in y ) / ( change in x )
(-2,4) and (-2,6)
slope = +%28+6+-+4+%29+%2F+%28+-2+-%28-2%29+%29+
slope = +2+%2F+0+
This is infinite slope, meaning a vertical line.
---------------
(-25,4) and (-2,8)
slope = +%28+8+-+4+%29+%2F+%28+-1+-%28-25%29+%29+
slope = +4+%2F+24+
slope = +1%2F6+
This slope is oblique to a vertical line
