anonymous · Answer

okay so you graph it . put the points in the graph and you can calculate the slope. Or just do (xone - xtwo)/(yone-ytwo). which is 0

anonymous · Answer

i lied not zero

hartnn · Answer

or use the slope formula
The slope of the line through points (x1,y1) and (x2,y2) is given by :
$\huge m=\frac{y_1-y_2}{x_1-x_2}$
now,just put the values and find m.

anonymous · Answer

its undefined

anonymous · Answer

cuz it is a vertical line

mrnood · Answer

because x2-x1 = 0 the formula above (hartnn) is not defined (cannot divide by zer0)
so oyu have your answer.
The 2 x values are the same - the line is vertical - it has no 'slope'
