# What is the slope of the line passing through the following points: # (1,3) ; (1,-2)#?

##### 2 Answers

#### Explanation:

#"calculate the slope m using the "color(blue)"gradient formula"#

#•color(white)(x)m=(y_2-y_1)/(x_2-x_1)#

#"let "(x_1,y_1)=(1,3)" and "(x_2,y_2)=(1,-2)#

#rarrm=(-2-3)/(1-1)=-5/0#

#"since division by zero is undefined then slope is undefined"#

Slope=undefined; vertical line

#### Explanation:

The slope is the change in the y-coordinates over the change in x-coordinates. The formula

The formula gives an undefined slope meaning that the line crossing the two points is vertical.
