#"slope is undefined"#

Explanation:

#"to calculate the slope use the "color(blue)"gradient formula"#

#color(red)(bar(ul(|color(white)(2/2)color(black)(m=(y_2-y_1)/(x_2-x_1))color(white)(2/2)|)))#
where m represents the slope and # (x_1,y_1),(x_2,y_2)" 2 coordinate points"#

#"the points are " (x_1,y_1)=(4,6),(x_2,y_2)=(4,0)#

#rArrm=(0-6)/(4-4)=(-6)/0#

#"division by zero is undefined and so the slope is undefined"#

#"this means that the line joining the points is vertical"#
